Answer:
a salt
Explanation:
compounds are made of molecules but we need to mention the type of compound formed.
Answer:
m = 1538.5 g
Explanation:
To answer this question, use the equation for specific heat:
Where q is the total heat energy, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the temperature change.
You will be expected to know the specific heat of water, which is 4.186 J/g/C. Using the information in the question:
The final answer, 1538.5 g, is closest.
Answer:
1: energy
2: converts
Kinetic energy is either 3 or 4, those questions are really similar.
Yes. Compounds can have different properties than the elements that go into them.
EXAMPLE: water is a polar liquid, while pure hydrogen and pure oxygen are both nonpolar gasses.
Answer:
1+
Explanation:
the number of protons tells you which element it is in the periodic table, you can notice that there is 1 less electron that then there is protons which means that the element had to give 1 electron away. When you get rid of 1 e- you have 1 proton more that electrons so that's why it's 1+
also the element is Cr
