NISA [10]3 years ago
7 0

Answer:

Alpha particles, Beta particles and Gamma rays

Explanation:

The emission of particles when a radioactive atom decays is called radioactivity.

An atom is radioactive as a result of unstable nucleus. This unstable nucleus of the atom disinintegrates and leads to emission of Alpha particles, Beta particles and gamma rays.

Alpha particles contain 2 protons and 2 neutrons. They are positively charged

Beta particles are negatively charged

Gamma rays are electromagnetic waves with short wavelength

C3H8 +502 + 3CO2 + 4H2O
astra-53 [7]

Answer:

Explanation:

first, you calculate the amount of O2 in moles:

98.0 ÷ 32 = 3.0625

second, the ratio if O2/C3H8 is 5 so you need to calculate O2 in moles with that:

3.0625 ÷ 5 = 0.6125

third, the amount of CO2 in moles also can be calculate by the ratio of C3H8/CO2 which is 3

0.6125 × 3 = 1.8375

then multiply CO2 in moles by its molar mass which is 44 g/mol

1.8375 × 44 = 80.85g

A 50.0 mL sample of 12.0 M HCl is diluted to 200 mL. What is true about the diluted solution?
kobusy [5.1K]

The concentration of the solution reduces and the number of moles of solute isn't affected.

Data;

  • V1 = 50mL
  • C1 = 12.0M
  • V2 = 200mL
  • C2 = ?
<h3>Facts about the diluted solution</h3>

1. When the solution is diluted, the concentration changes and this time, the concentration reduces.

Using dilution formula

c_1 v_1 = c_2 v_2\\12 * 50 = c_2 * 200\\c_2 = \frac{600}{200} \\c_2 = 3M

The concentration of the solution reduces.

2. The number of moles remains the same.

When a solution is diluted, the number of moles remains the same because there's no change in the mass of the solute.
