The heavy player hits the lighter player with more force.

The lighter player gets hurt more after the collision

Explanation:

A heavy player will hit a light player with more force and eventually, the lighter player will get hurt the more after the collision.

Force is a function of mass and acceleration of a body;

Force = mass x acceleration

We can see that the more the mass and acceleration of a body, the more the force they can exert.

It is obvious that the mass of the heavier player is more than that of light player. Therefore, it exerts more force on the other one.

Also, the lighter player will get hurt the more after collision. The momentum with which the heavier football player hits the light one is very great. After the collision, the light footballer will most definitely change acceleration and direction of traveling.

Given the equation: 2H2 + O2 → 2H2O, how many moles of oxygen are needed to react with 13 moles of hydrogen

bulgar [2K]

Explanation:

2H2 + O2 = 2H2O

2mol. 1mol. 2mol

2mol reacts with 1mol

13mol reacts with x

x=13mol × 1mol

2mol

x= 13mol

2mol

x= 6.5mol of oxygen

Which of the following is not among the advantages of generating nuclear energy?

WARRIOR [948]

While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.

Explanation:

Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.

How many grams of calcium phosphate can be produced when 89.3 grams of calcium chloride reacts with excess sodium phosphate?

larisa86 [58]

Balanced chemical equation is
3CaCl2 +2Na3PO4-->6NaCl +Ca3(PO4)2
moles of CaCl2 =89.3g/[ (35.5x2) +40]=0.805moles
from the equation above the ratio of CaCl2 to Ca3(PO4)2 is 3:1 therefore the moles of Ca3(PO4)2 is 0.809/3=0.268moles
mass is therefore 0.268 x310.18(R.F.M of Ca3(PO4)2 ) =83.23grams

The smallest unit that can exist as an element and still have the properties of that element is a(n): electron proton neutron at

Alex

Answer:

Atom

Explanation:

An atom is the smallest quantity of any given element.

An atom includes a nucleus (which includes protons and neutrons) around which are located the electrons. That's that specific assembly of nucleus and surrounding electrons that form an atom and define which element it is.

So,

electron: negative charge in orbit of the nucleus

proton: positively-charged particle inside the atomic nucleus

neutron: neutral particle inside the atomic nucleus

atom: ensemble of the nucleus and electrons, defining a given element.
