Answer:
Gay-Lussac’s law
Explanation:
Gay's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
B. Summing Force
C. Unbalanced Force
D. Net Force
PLZZ HELP ME A.S.A.P!!
Answer:
D. Net Force
Explanation:
The overall force on an object is called the net force. When the net force is zero, the forces are balanced, and when it is nonzero, the forces are unbalanced.
The correct answer is D. Net Force.
The overall force on an object is called the net force. It is the vector sum of all the individual forces acting on the object. When the net force is zero, the forces are balanced and the object is either at rest or moving at a constant velocity. When the net force is nonzero, the forces are unbalanced and the object will accelerate in the direction of the net force.

, and the chemical formula of the compound is
Answer:
a) oxidation number of chromium is +3
b) formula of the compound is Cr2(SO4)3
Explanation:
From the name of the compound, we can see that the oxidation state of chromium is +3
We know the sulphate ion to to be SO4^2-
According to the rules of writing the formula of compounds from valencies, the valency of chromium is 3 while that is the sulphate ion is 2.
The both species can now exchange valency
Cr2(SO4)3------- This is the correct formula of the compound
Answer:
The oxidation state is +3.
chemical formula of compound is Cr₂(SO₄)₃.
Explanation:
Calculation of oxidation state:
Cr₂(SO₄)₃
Cr= ?
The oxidation state of SO₄ = -2
2x + 3( -2) = 0
2x - 6 = 0
2x = 6
x = 6/2
x= 3
The oxidation state of Cr is +3.
The Cr has valency of 3 so three SO₄ will require while the valency of SO₄ is 2 so two Cr will require.
Cr×2 and SO₄×3
Cr₂(SO₄)₃
we know that oxidation state of Cr is +3 so (3×2) = 6
and the oxidation state of SO₄ is -2 so (-2× 3) = -6
6-6= 0
The overall charge is 0, the compound will be neutral.

brainly is stubborn and wont let me put the answer so ignore this because I have to add at least 20 letters :)
Answer:
Areas at high latitudes have the coldest water.
Explanation:
Surface water receives its heat from the sun.
I took the test and it was right 100% :)

Answer:
Planet: The object orbits the sun
Not planet: The object is a satellite
Planet: The regions surrounding the object are free from debris
Not Planet: The object is triangular in shape.
Explanation:
A planet is characterized as:
Spheroidal (or at least big enough to be round-ish)
It should orbit the sun (not other planets, so satellites like the moon is not considered as a planet)
It should have no debris, or cleared of debris around its orbit
Although there is now the dwarf planet category, it satisfies almost all charateristics to be considered a planet, except the cleared of debris part.
Answer:
Planet: The object orbits the sun
Not planet: The object is a satellite
Planet: The regions surrounding the object are free from debris
Not Planet: The object is triangular in shape.
