I am an alkali metal located in the third period of the periodic table. Who am I?

Answers

Answer 1

Answer:

Magnesium

Explanation:

It's an alkali metal and is in the third period on the period table. I'm sure

Answer 2

The alkaline earth metal found in period 3 of the periodic table is magnesium.The lightest structural metal is magnesium (Mg), an alkaline-earth metal from Group 2 (IIa) of the periodic table.

I am an alkali metal located in the third period of the periodic table. Who am I?

Six chemical elements in Group 1, the periodic table's leftmost column, make up the alkali metals.They are francium (F), cesium (Cs), rubidium (Rb), potassium (K), sodium (Na), and lithium (Li) (Fr). One of the chemical elements in the third row of the periodic table of the chemical elements is referred to as a period 3 element. Magnesium is regarded as a metal because it is a member of group2.Acid and metals react to produce salt and hydrogen gas.As a result, magnesium interacts with diluted hydrochloric acid to produce magnesium chloride (salt) and hydrogen gas. Magnesium is a silvery, light metal that makes up 2% of the Earth's crust but is not present in nature.Only in combination with other elements like carbon, calcium, and oxygen, as in the common mineral dolomite, could this versatile element naturally arise. Magnesium is a cofactor in more than 300 enzyme systems that affect a variety of biochemical processes in the body, including as protein synthesis, blood glucose control, blood pressure regulation, and muscle and nerve function [1-3].Magnesium is necessary for the oxidative phosphorylation, glycolysis, and generation of energy. Magnesium supports muscle and neuron function as well as energy synthesis in the body, among many other vital functions.Typically, low magnesium levels don't result in any symptoms.On the other hand, persistently low levels can raise your risk of osteoporosis, type 2 diabetes, high blood pressure, and heart disease. For the majority of individuals, daily doses under 350 mg are safe.The adverse effects of magnesium can include nausea, vomiting, diarrhea, and upset stomach in some people.Magnesium is POSSIBLY SAFE UNTIL TAKEN IN VERY HIGH AMOUNTS (more than 350 mg daily).

1. How much energy is required to heat 32.5g of water from 34°C to 75°C?

Answers

Answer:

5.850 kJ (of heat energy)

Explanation:

What we need:

[] The mass of the material = m = 32.5g  

[] The temperature change that occurs = ΔT = 43

() 75 - 34 = 43  

[] The specific heat capacity of the material = c

() This is the amount of heat required to raise 1 gram of that substance by 1°C

() For water, this is 4.186Jg°C

The equation to use:

Q = m * c * ΔT

Q = 32.5 * 4.186 * 43

Q = 5849.935 J

Q = 5.850 kJ

Answer:

[tex]\boxed {\boxed {\sf 5569.85 \ Joules}}[/tex]

Explanation:

We are asked to find how much energy is required to heat a sample of water.

We will use the following equation:

[tex]q= mc \Delta T[/tex]

The mass of the water is 32.5 grams. The specific heat capacity of water is 4.18 Joules per gram degree Celsius.

The change in temperature is the difference between the final temperature and the initial temperature. The water's temperature is raised from 34 degrees Celsius to 75 degrees Celsius.

ΔT= final temp - inital tempΔT = 75 °C - 34 °C = 41 °C

Now we know all three variables:

m= 32.5 g c= 4.18 J/g °C ΔT = 41 °C

Substitute the values into the formula.

[tex]q= (32.5 \ g)(4.18 \ J/g \textdegree C)(41 \ \textdegree C)[/tex]

Multiply the first 2 numbers together. The units of grams cancel.

[tex]q= 135.85 \ \ J/ \textdegree C(41 \ \textdegree C)[/tex]

Multiply again. This time, the units of degrees Celsius cancel.

[tex]q= 5569.85 \ J[/tex]

5,569.85 Joules of energy are required.

Describe: The behaviors scientists use in their work.

Answers

Answer:

If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore.

Scientific inquiry uses evidence from observations and investigations to create logical explanations to answer questions related to science. Scientific inquiry is different from the scientific method. ... Scientific inquiry helps you think outside the box to understand the natural world.

Unlike social scientists, behavioral scientists collect empirical data and use experimental methods, including testing, controls and manipulated settings.

what is neutralisation??​

Answers

Answer:

Acid + Base -------> Salt + Water

Explanation:

The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.

Example:

HCl + NaOH ----------> NaCl + H2O

HCl is hydrochloric acid.

NaOH is sodium hydroxide which is a base.

NaCl is sodium chloride which is a salt.

H2O is water.

1340.40 grams of Iron is made to react with nitric acid, find mass of ferri nitrite produced. Use the given equation 2 Fe + 6HNO3 2Fe (NO3 + 3H₂ ​

Answers

The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g

Balanced equation

2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂

Molar mass of Fe = 56 g/mole

Mass of Fe from the balanced equation = 2 × 56 = 112 g

Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole

Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g

SUMMARY

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

How to determine the mass of Fe(NO₃)₃ produced

From the balanced equation above,

112 g of Fe reacted to produce 484 g of Fe(NO₃)₃

Therefore,

1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃

Thus, 5792.44 g of Fe(NO₃)₃ were obtained from the reaction
