Shontal compared some of the properties of a marble to a piece
of wood. She placed a marble and a piece of wood in a bucket filled
with water. Shontal observed the wood floating on top of the water,
but the marble sank to the bottom of the bucket. Which statement
best explains why the marble and piece of wood acted differently in
the water?

Answer:

shift to restore equilibrium

Explanation:

Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.

Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.

Equilibrium is the state of a reversible reaction when:

• two opposing reactions occur at the same rate;

• the concentrations of reactants and products are constant

Explanation:

How much energy is required to raise the temperature of 3 kg of aluminum from 18°C to 23°C? Use the table below and this equation: Q=mcΔT

Answer:

I think it would be a liquid.

Explanation:

If the temperature hits a certain point, it will turn to ice. If the ice gets exposed to heat, it will melt and return back to it's natural form, a lqiuid. If the liquid is exposed to enough heat, it will evaporate. Not sure if this is right, but I tried my best!  

Answer:

B. rubbing your hands together to get warm,

Explanation:

Rubbing your hands together warms them by converting work into thermal energy.

Hope it helps ;)

Answer:

I think its A

Explanation:

Because a lamp has a lightbulb and it produces wasted heat and is thermal energy

Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams

This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

hope this helps have a awesome night/day❤️✨

Explanation:

There are 36 grams in 3.00 moles of carbon.

Answer:

C) The puck gradually slows down because friction would be acting on it.

Explanation:

It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

Answer:

like what happens In 3 hours

This is a combined gas law problem, according to which

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

where P is the pressure of the gas, V is the volume of the gas, and T is the temperature of the gas, and the subscripts 1 and 2 correspond to the initial and final conditions of the gas. In this problem, we are given the initial pressure, volume, and temperature of the gas in the balloon:

P₁ = 1.0 atm

V₁ = 1.8 L

T₁ = 295.15 K (K = °C + 273.15).

Moreover, we are given the final pressure and temperature of the gas in the balloon.

P₂ = 0.86 atm

T₂ = 281.15 K.

What we want to find is the final volume, V₂, which we can obtain by rearranging the combined gas equation to solve for V₂:

[tex]V_2=\frac{P_1V_1T_2}{T_1P_2} = \frac{(1.0 \text{ atm})(1.8 \text{ L})(281.15 \text{ K})}{(295.15 \text{ K})(0.86 \text{ atm})} \\ V_2 = 1.99 \text{ L}[/tex]

This answer has three significant figures. However, the question as written would warrant an answer that comprises one significant figure (as 8 °C has only one sig fig). In that case, the answer would be 2 L. If the answer is to be given to two significant figures, the volume would then be 2.0 L.

Answer:

The answer for this question is A. butylcyclohexane

Explanation:

Choose letter A

You welcome have a nice day.

Name of the given compound is butyl cyclohexane.

Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.

In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.

Hence name of the compound is butyl cyclohexane.

Answer:

The answer to your question is: 71 g of Chlorine

Explanation:

Na = 46 g

Cl = ?

NaCl = 117 g

Equation

                     2 Na     +     Cl₂   ⇒   2 NaCl          

                     46g              X              117g

If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then

                   mass Na + mass Cl₂  = mass NaCl

                    46 g + X = 117

                    X = 117 - 46

                   x = 71 g of Chlorine

With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.

Answer:

Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease.

With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.

Explanation:

High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as:

Chest pain. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease.

Heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site — blocking the flow of blood or breaking free and plugging an artery downstream. If blood flow to part of your heart stops, you'll have a heart attack.

Stroke. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain.
