Answer:

a. Solar

Explanation:

Solar energy causes water to evaporate, which is the driving force of the water cycle. Water from the ocean evaporates and comes back down as rain and it gives life to the Earth and so it continues.

Answer : A. Solar

Explanation : The sun provides its solar energy which causes liquid and frozen water to evaporate into water vapor. This water vapor rises into the sky to form clouds, and from there on the clouds move over the globe and drop rain and snow, and from there on the water cycle continues.

1. Most of the chemicals included in your General Chemistry Lab kit can be discarded down a drain. Describe a situation in which

Tju [1.3M]

Answer: Chemicals like acids and bases are harmful and must be neutralized before draining.

Explanation:

A strong acid or strong base is required to be diluted or neutralized before it is discarded in the drain as if is discarded without diluting and neutralization it can spill and splash from sink or drain and can harm people in chemistry lab, moreover the fumes of the discarded chemical on spilling can cause respiratory tract burning and can even cause fire hazard so it must be converted into less harmful form and then must be drained.

Which would have more volume? A mass of mercury or the same mass of bromine. The density of mercury is 13.5g/ml. The density of

deff fn [24]

Explanation:

Given that,

The density of mercury is 13.5 g/mL

The density of Bromine is 3.12 g/cm³

It is mentioned that Mercury and bromine have the same mass. Let d₁,d₂ are the density of Mercury and Bromine. V₁ and V₂ are their volumes. So,

$\text{density}=\dfrac{\text{mass}}{\text{volume}}$

$\text{mass}=\text{density}\times \text{volume}$

Since, mass is same.

So,

$d_1V_1=d_2V_2\\\\\dfrac{d_1}{d_2}=\dfrac{V_2}{V_1}\\\\\dfrac{13.5}{3.12}=\dfrac{V_2}{V_1}\\\\4.32=\dfrac{V_2}{V_1}\\\\V_2=4.32\times V_1$

Hence, the volume of bromine is more than that of mercury. It is 4.32 times of the density of mercury.

kondaur [170]

When cooking frozen cheese ravioli, you should use three quarts of water instead of one so that the raviolis have room to move around in the boiling water and so that while they are moving around, they will not stick to each other or the pan.

Sveta_85 [38]

Answer: The equilibrium constant for the above reaction is 1.31

Explanation:

We are given:

Initial moles of nitrogen gas = 0.3411 moles

Initial moles of hydrogen gas = 1.661 moles

Equilibrium moles of nitrogen gas = 0.2001 moles

For the given chemical reaction:

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)$
