Answer:

Hi there!

Your answer is:

B. Water shrinks when it freezes

What can you conclude about these two reactions based on the chemical equations? Reaction A: 6CO2(g) + 6H2O(l) + sunlight ? C6H1
OlgaM077 [116]

Given reactions:

(A)   6CO2(g) + 6H2O(l) + sunlight → C6H12O6(aq) + 6O2(g)

(B)  2H2(g) + O2(g) → 2H2O(g) + energy

Exothermic reactions are those which proceed with the release of heat/energy. In contrast, endothermic reactions proceed with the absorption of energy in the form of heat or light.

Since reaction A required sunlight, it is endothermic. Reaction B releases energy, hence exothermic

Ans: (B)

A is endothermic

B is exothermic

By what number do you multiply 588 to get your weight in newtons on jupiter?
erica [24]

The number that will be multiplied by 588 to get one's weight in Newtons is 2.5 considering that the mass of the individual is 60kg.

<h3>How to calculate weight?</h3>

Weight is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).

The weight of an object can be calculated by multiplying the mass of the object by acceleration due to gravity of the location.

According to this question, we would consider an individual with a mass of 60kg. The acceleration due to gravity on Jupiter is 24.5 m/s².

Weight = 60kg × 24.5 m/s² = 1470N

This means that the number to be multiplied by 588 to get weight of 1470N is 2.5.
