Subatomic particle that has mass nearly equal to that of a proton, but carries no electrical charge

Answers

Answer 1

Answer: The answer is the neutron. It is a subatomic particle with no net electric charge and its mass is approximately equal to the mass of a proton. Protons and neutrons constitute the nucleus of an atom and collectively they are called as nucleons.

A reaction contains two reactants, A and B. If A is doubled, there will be a greater number of effective collisions between reactants.

Answers

Answer:

True

Explanation:

The complete question is:

"A reaction contains two reactants, A and B. If A is doubled, there will be a greater number of effective collisions between reactants. TRUE FALSE"

Collision Theory indicates that chemical reactions take place because molecules, atoms or ions collide with each other.

Furthermore, the molecules must collide effectively, that is, not all reagent collisions lead to product formation. Effective shock means that the reagent molecules have enough kinetic energy at the time of the shock for their bonds to break and product bonds to form. In addition, the molecules of the reagents must be properly oriented for the reaction to take place.

As the concentration increases, the number of shocks increases. In other words, by increasing the concentration of the reactants, the probability of collision between their molecules increases, and therefore the number of effective collisions.So the statement is true-

The statement is true. Adding more of the reactants will increase the frequency of effective collisions between reactant given that the other reactant is supplied in excess. Adding more of the reactant will favor the forward reaction or the formation of more products.

If the atomic radius of a calcium crystal is 180 pm, what is the length of the edge of the unit cell? (the calcium crystal forms

Answers

The edge length of a a unit cell of calcium crystal is 509.12 pm.

Structure of the Calcium crystals

Calcium crystal has a face center cubic (FCC) structure.

Edge length of the unit cell

The edge length of the unit cell for face center cubic (FCC) structure is given in the following formula;

a = 2r√2

where;

a is edge length
r is the radius

a = 2 x 180 x √2

a = 509.12 pm

Thus, the edge length of a a unit cell of calcium crystal is 509.12 pm.

Calcium crystal has a face center cubic (FCC) structure. For FCC structure,
relation between edge length (a) and radius (r) is
a = 2√2 r
Given: r = 180 pm
Therefore, a = 2√2 180
= 2 x 1.141 x 180
= 410.76 pm

The length of the edge of the Ca unit cell is 410.76 pm.

What is the pressure of 64 grams of O2 in a 1L container at a temperature of 10°C?

Answers

So PV=nRT
P=?

We know that:
-V=1L
-R=8.314kPa•L/mol•K
-T=10°C (we need to converse °C in K so 10+273) =283K
For n, we know that we have 64g of O2 and were looking for the quantity of mole in these 64g. 1 mole of O2 is 15.999g so 64g would be 4.0mol ((64g • 1mol)/15.999g) so n=4.0

P•1L= 4.0mol • 8.314kPa•L/mol•K • 283K
P • 1L = 9411
P = 9411/1L
P = 9411kPa
