Answer:

The correct answer is option b.

Explanation:

To calculate density of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Mass of an object = 10 g

Volume of an object  = 5 mL

Density of an object = d

Putting values in above equation, we get:

d=\frac{10 g}{5 mL}=2 g/mL

2 g/mL is the density of an object that has a mass of 10 g and a volume of 5 mL.

velikii [3]
The balanced chemical reaction is expressed as:

<span>C3H8 + 5 O2 -> 3 CO2 + 4 H2O

We are given the amount of water produced. We use this amount for the calculations. We do as follows:

16.3 mol H2O ( 1 mol C3H8 / 4 mol H2O ) = 4.075 mol C3H8 needed

Hi!


<u>The correct options would be: </u>

is an electron

is emitted from nucleus

has a -1 charge


Explanation:

A beta particle is a result of a neutron (a neutral particle) changing into two particles of opposite charges - a high energy electron (with a negative charge -1) and a positron (with a positive charge +1). Neutrons are present in the nucleus of an atom, and thus the beta particles are said to be emitted from the nucleus. They do have a charge, not zero, but it is not +2 and can only be either -1 or +1. This form of radiation is not electromagnetic energy because beta particles are massless, and do not travel at the speed of light (both being characteristics of electromagnetic radiation). Beta particles are not pure forms of energy.


Hope this helps.
