If the mass of a material is 78 grams and the volume of the material is 23 cm3, what would the density of the material be?

Paraphin [41]3 years ago

Density = mass / volume

Density = (78g) / (23cm^3)

Density = 3.4g/cm^3

By definition, density is mass per volume.

d=\frac{m}{v}

Plugging in the given values gives:

d=\frac{78 g}{23 cm^3} =3.3913\frac{g}{cm^3}

The only operation done in the problem is division, and both numbers have 2 significant figures, so this would be 3.4\frac{g}{cm^3} with correct significant figures.

Under which class of substitution reaction does this reaction appear to fall
liberstina [14]

This reaction is most likely to fall under SN2 because the thing called carbonication does not occur in SN1. The carbon forms a partial bond with the nucleophile during the intermediate phase and the leaving group. So for this question the reaction will fall under SN2.

A(n) _____ is equivalent to an electron. gamma ray omega particle alpha particle beta particle
ladessa [460]

Answer:

beta particle

Explanation:

Explanation:

Alpha beta and gamma radiations are the examples of ionizing radiations. When an atom is an excited state and having high energy, the atom is in unstable state. The excess of energy is released by the atom to get the stability. The released energy is in the form of radiations which may include alpha, beta, gamma, X-ray etc.

¹⁴₆C → ¹⁴₇N + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiations

Paul went to his friend's 2 km from his house, he used his bike and took him 9 minutes.
damaskus [11]

The average speed : 3.07 m/s

<h3>Further explanation</h3>

Given

d1 = 2 km

t1 = 9 min

d2 = 1.5 km

t2 = 10 min

Required

The average speed

Solution

Average speed = total distance : total time

total distance :

= d1+d2

= 2+1.5

=3.5 km

total time :

= t1+t2

= 9 min + 10 min

= 19 min

Average speed :

= 3.5 km : 19 min

= 0.184 km/min

= 3.07 m/s
