Answer:

1. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed

2.  However after pouring the water from one short glass into a tall glass,  to be the same amount after being poured into any other container

3. Yes, wood have a fixed shape. Explaination: The reason is that it's solid and solids have a definite volume and shape. ... They have shapes that do not change and volumes that can be measured

4. Water is known to exist in three different states; as a solid, liquid or gas. Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water

5. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Other examples of solids include wood, metal, and rock at room temperature

6. For example, water commonly exists in three states of matter: solid (ice), liquid (water), and gas (steam)

Explanation:

1. It will adopt its container's shape. Within a liquid, particles can move around, yet the volume is maintained because of the liquid's dense packing. Particles in gaseous stuff are arranged so haphazardly that neither their shape nor their volume can be determined.

The term liquid is defined as substance which is not solid but which flows and can be poured and take a shape of container. water is an example of liquid.

2. However, the same amount of water would be poured into any other container after being transferred from one short glass to a tall glass.

3. The shape of wood is fixed. It's solid, and solids have a distinct volume and shape, which explains why. They have measurements-able volumes and unchanging forms.

4. There are three recognized states of water: solid, liquid, and gas. Snow, rain, and clouds are all composed of water in some way. A snowflake is an accumulation of several ice crystals, a cloud is made up of microscopic water droplets and/or ice crystals, and rain is just liquid water.

5. When liquids or gases are chilled, solids can occasionally form; ice is an example of a cooled liquid that has solidified. At room temperature, solids also include wood, metal, and rock.

6. As an illustration, water typically exists in three states: solid (ice), liquid (water), and gas (steam).

Answer:

A. How much decay happens in each flashlight

Explanation:

In an experiment, the DEPENDENT OR RESPONDING VARIABLE is the variable that responds to changes being made to another variable called Independent variable. It is the variable that is measured by an experimenter.

In this question, an experiment was carried out to research the effect of sunlight on plastic decay. Three plastic flashlights were used for this experiment in which one was placed in a dark closet (control), and the others were placed in light at different times or intervals. However, the variable being measured or assessed is the decay of each flashlight. This means that "HOW MUCH DECAY HAPPENS IN EACH FLASHLIGHT" is the dependent variable.

Answer: c

Explanation:

Answer:

You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water in a beaker.

Explanation:

Capital M stands for molarity, or moles/liter. So 3 M MgO means 3 moles per liter of MgO.

1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] = 3 moles MgO

This means you need to measure 3 moles MgO to put into 1 Liter of water.

But you don't know how much that is, so you need to convert moles to grams.

First you need to find how many grams are in 1 mole of MgO.

You can search the molar mass of MgO online to get: 40.3044 g

But if you don't have the internet, use the periodic table to add the masses of Mg and O: 24.305 g + 15.999 g = 40.3044 g

Then write the fraction so that the units cancel out, so you get grams by itself on the top of the fraction.

1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] × [tex]\frac{40.3044 g MgO}{1 mole MgO}[/tex] = 120.9132 g MgO

You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water.

We will prepare 1 L solution of 3 M MgO, by dissolving 120.91 grams of MgO in 1 litre of water.

Molarity is define as the no. of moles of solute dissolve in per liter if solvent or solution & it is represented as:

M = n / v

In the question, it is given that:

Molarity of MgO = 3M i.e. 3 moles of MgO is present in 1 liter of solution.

So, we have moles of MgO = 3 moles

Now, we convert moles of MgO to grams to know how much of solute is required, in the following manner:

n = W / M, where

M = molar mass of MgO = 40.30 g/mole

W = to find?

W = 3 mole × 40.30 g/mole = 120.91 grams

Hence, 120.91 grams of MgO is required.

The position where a Period 4 element that is also a metal with three valence electrons would be located is: B) Position 15.

A periodic table can be defined as an organized tabular array of all the chemical elements, which is typically arranged in order of increasing atomic number or number of protons (in rows).

In Chemistry, a periodic table comprises seven (7) rows and eighteen (18) columns. Also, all chemical elements are arranged (grouped) on the periodic table based on their atomic number (number of protons).

In this context, the position where a Period 4 element that is also a metal with three valence electrons would be located is Position 15 on the periodic table.

42.3moles

Explanation:

The chemical equation given in this question is as follows:

H2 + O2 → H2O

However, this equation is unbalanced, the balanced chemical equation is as follows:

2H2 + O2 → 2H2O

This equation shows that;

2 moles of hydrogen gas (H2) will produce 2 moles of water (H2O)

Hence, If 42.3 moles of water (H2O) are produced, 42.3 × 2/2

= 42.3moles of hydrogen was reacted.

Answer:

A. Water

Explanation:

Virtually every known substance can be referred to as MATTER, as long as it has weight and occupies space. Matter can exists in three different forms namely: solid, liquid and gaseous states.

However, each state of matter has its own unique property that characterizes it. WATER is the only matter that can exists in the three different states as follows:

- LIQUID - WATER

- SOLID - ICE

- GASEOUS - STEAM OR VAPOUR.

Answer: Chromium is less reactive as compared to Aluminium as it can not easily electrons as aluminium.

Explanation:

The arrangement of metals in a series according to the decreasing order of their reactivity is called reactivity series.

The metals that are placed above hydrogen are more reactive and those below hydrogen are less reactive.

A metal placed above another metal can displace lower metal from its salt solution. Thus a metal placed above in series is more reactive than metals placed below it.

As aluminium can easily lose electrons as compared to chromium , it is more reactive than Chromium.
