Group 7a would have an ion charge of -1 because it has 7 valence electrons and it wants to gain one more electron(which is negative) to have a full shell of 8
Answer:
Explanation:
Kory goes outside to grill some hamburgers. He tells Ethan that when you cook meat, a chemical reation is taking place. Ethan says "That's perpostrous!" Is Kory Correct??
absolutely Kory is correct
evidence of a chemical reaction are
new odor and or taste
change in color
signs of bubbling
direct effect of temperature on rate of change
evidence of a new substance being formed
we observe all these when we grill meat.
Answer:
leave little space between the molecules.
Explanation:
Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.
In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".
They are quite unlike gases where there is a lot of space between gas molecules.
Answer:
n = 6.06 x 
mol
Explanation:
n =?
m = 3.06 x 10-³ g
M (H5) = 5 x 1.01 (Since we only want hydrogen)
Atomic mass of C = 12.01
Atomic mass of H is 1,01, etc.
Having this data, we can use the Molar mass formula and change it so we can know the quantity of matter (n) in moles, and we just replace it.
M = 
⇔ n = 
⇔ n = 
⇔ n = 6.06 x mol
Note: The numbers I've used may be different from yours, by a small difference. I don't know if it's the case, but hope it helped.
Answer: Ionic Bond
Explanation: The electrostatic attraction that binds oppositely charged ions together. alloy. a mixture composed of two or more elements, at least one of which is a metal.
Hope this helped!
