Answer:
The compound name is Silver nitrite
Explanation:
Answer:
<u>-16200J</u>
Explanation:
(257J/g)(62.9g)
eliminate the variables
u get 16165.3
go to 3 significant digits
u get 16200
and since it is freezing we are taking out energy so it would be
-16200J
Answer:
There's virtually no pure hydrogen on Earth because it's so reactive. Most hydrogen is made from methane [natural gas] in a process that produces carbon dioxide and other greenhouse gases. Hydrogen can also be made from water using electrolysis, but that requires electrical energy.
Explanation:
The difference between speed and velocity is that speed is the time rate at which an object is moving along a path. While velocity is the rate and direction of the object’s movement.
if something is travelling at a constant velocity are the forces balanced or unbalanced?
Unbalanced
if something changes motion, are forces balanced or unbalanced?
Unbalanced. If the forces on the object is equal and in opposite directions, then the forces are balanced, then there would be no change in motion
what are the three ways to accelerate?
1. A change in velocity
2. A change in direction
3. A change in both velocity and direction
Answer:
d. magnesium sulfide, mgs
Explanation:
Ionic bonds or also called eletrovalent bond is one of the chemical bonds that forms between the atoms of molecules or compounds. It is the kind of bond that forms between a positively charged atom and a negatively charged atom. The positive atom transfers electrons to the negative atom.
In this question, Magnesium Sulfide, MgS is a compound whose atoms are held together by ionic bonds. The magnesium ion (cation) transfers its two valence electrons to the sulfur ion (anion) to form the stable MgS.
