the same
Explanation:
Within the nucleus of individual atoms of the same element, the proton number is the same.
All atoms of the same kind from the same element have the same number of protons.
The number of protons does not change, it remains fixed after a chemical reaction.
Different elements have different number of protons that typifies and makes them unique.
But atoms of the same element have the same number of protons in them.

Answer:
The answer is
<h2>25 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of CCl4 = 40g
Density = 1.6 g/mL
The volume is

We have the final answer as
<h3>25 mL</h3>

A beta particle is an electron and it has a -1 charge and zero mass.
Beta decay by
emitting an electron is called as β⁻
decay. When this happens, a neutron of the element converts into a proton by
emitting an electron. Hence, the mass of daughter nucleus is same as parent
atom but atomic number/number of protons is higher by 1 than atomic number of
parent atom.
In a β⁻ decay, the symbol is used as ₋₁⁰β or ₋₁⁰e.
-1 is for charge
<span> 0 is for the mass of the particle

Answer:
He will decide which drink is to be served to whom, by the use of litmus paper.
Explanation:
The litmus paper is the most common indicator to determine the acidity or basicity of a solution. Blue litmus paper changes its color to red when a solution changes from basic to acidic while red litmus paper changes its color to blue when the opposite occurs (acid → basic).
First of all the litmus paper strip, pH indicator, is immersed in a solution and allowed to pass between 10 and 15 seconds while keeping the strip submerged. Afterwards it is removed, and then the strip compares the color. If the color is diffuse, there is a color scale where it is determined which solution has alkaline or acidic pH
