The correct answer is potential energy.

Potential energy is when an object can store energy as the result of its position.

Gravitational potential energy is the energy stored between an object and the Earth.

Elastic potential energy is the energy stored in objects that are compressed or stretched.

Chemical potential energy is the energy stored in the bonds between atoms.

What is another name for a condensation reaction?

defon

The other name for a condensation reaction would be dehydration reaction. This reaction happens when two molecules or compounds react forming a larger molecule and a small H2O molecule. From the name itself, water should be produced.

How much heat in j is giving out when 85.0g of lead cools from 200.0 c to 10.0c

photoshop1234 [79]

Answer:

q = - 2067.2 J of Heat is giving out when 85.0g of lead cools from 200.0 c to 10.0 c.

Explanation:

The Specific Heat capacity of Lead is 0.128 $\frac{J}{g\ ^{0}C}$

This means, increase in temperature of 1 gm of lead by $1 ^{0}\ C$ will require 0.128 J of heat.

Formula Used :

$q = m.c.\Delta T$

q = amount of heat added / removed

m = mass of substance in grams = 85.0 g

c = specific heat of the substance = 0.128

$q = m.c.\Delta T$ = Change in temperature

= final temperature - Initial temperature

= 10 - 200

= - $190 ^{0}\ C$

put value in formula

q = - $85\times 0.128\times 190$

On calculation,

q = - 2067.2 J

- sign indicates that the heat is released in the process

Aleonysh [2.5K]

Answer:

the reactivity and the valence electrons

Explanation:

the reactivity of the elements would have played a significant role in why such elements were grouped together. the number of valence electrons dictates how reactive an element is - the less valence electrons the more reactive it is. the column, group 1 in which these elements are put together in, show that each of the elements have 1 valence electrons and are therefore reactive.

you can go on to further explain what valence electrons are, explain what the group numbers are associated with the valence electrons and how valence electrons effect reactivity. further this, talk about how the three elements have the same number of valence electrons and therefore were grouped together

When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solutio

8090 [49]

Answer:

Volume of stock solution needed = 6.0299 mL

Explanation:

Dilution consists of lowering the amount of solute per unit volume of solution. It is achieved by adding more diluent to the same amount of solute.

This is deduced when thinking that both the dissolution at the beginning and at the end will have the same amount of moles.

Data:

M1 = 6.01 M stock solution concentration

M2 = 0.3624 M diluted solution concentration

V2 =100 mL diluted solution volume

V1 = ? stock solution volume

M1 * V1 = M2 * V2

$V1=\frac{M2*V2}{M1} =\frac{0.3624M*100mL}{6.01M} =6.0299 mL$
