What would happen if the energy from the sun was not reflected back
Savatey [412]
<h2>It would have an effect very much like over inflating a balloon. The space inside the Dyson Sphere would be overfilled with energy and the Sphere would be assaulted by energy that exceeds it's capacity to reflect it.</h2>

Write a balanced chemical equation for the fermentation of sucrose (C12H22O11) by yeasts in which the aqueous sugar reacts with
bogdanovich [222]

Answer:

C_{12}H_{22}O_{11}(aq)+H_{2}O(aq)=4C_{2}H_{5}OH(aq)+4CO_{2}(g)

Explanation:

1. First write the formula of each compound:

Sucrose : C_{12}H_{22}O_{11}

Water : H_{2}O

Ethyl alcohol : C_{2}H_{5}OH

Carbon dioxide : CO_{2}

2. Write the equation with the reactants on the left and the products on the right:

C_{12}H_{22}O_{11}+H_{2}O=C_{2}H_{5}OH+CO_{2}

3. Put the states of matter of each compound in the reaction, as the problem says:

C_{12}H_{22}O_{11}(aq)+H_{2}O(aq)=C_{2}H_{5}OH(aq)+CO_{2}(g)

aq = aqueous solution

g =  gas

4. Balance each element.

The number of each atom must be the same on the left and on the right.

C_{12}H_{22}O_{11}(aq)+H_{2}O(aq)=4C_{2}H_{5}OH(aq)+4CO_{2}(g)

Which two statements describe what happens to the nuclei of atoms during a fusion reaction? O A. Large nuclei break apart into t
pashok25 [27]

Answer:

D. Nuclei with small masses combine to form nuclei with larger masses.

B. A small amount of mass in the nuclei that combine is converted to energy

Explanation:

A nuclear fusion, in contrary to fission, is the process by which the nuclei of two atoms combine to form a much larger atom with a large nuclei. Likewise, during a fusion reaction, a large amount of energy is released from the small amount of mass in the nuclei (two) that combines.

According to this question, the following are true of a fusion reaction:

- Nuclei with small masses combine to form nuclei with larger masses.

- A small amount of mass in the nuclei that combine is converted to enormous energy.

Calculate the freezing point of a solution containing 5.7 % kcl by mass (in water).
laila [671]
5.7% KCl  is 94.3 % water.
Therefore, for 1000 g of water the mass of KCl will be (1000× 5.7)/94.3 = 60.445 grams.
1 mole of KCl is equal to 74.55 g, 
therefore, 60.445 g will be 60.445/74.55 = 0.8108 mole of KCl
Hence, 0.8108 moles of KCl should release twice that number of moles 1.6216 moles ions.
Having 1.6216 moles of KCl ions dissolved in 1000g of water, gives us 1.6216 molar if solution.
Using the freezing point depression constant of water.
dT = Kf (molarity)
dT = (1.86 C/ molar) (1.6216 m)
dT = 3.016 C drop in freezing point
Therefore, it should freeze at - 3.016 Celsius
