The correct answer is C. A positive calcium ion and a negative oxygen ion

Explanation:

In chemistry, an ionic bond occurs as ions with opposite charges attract each other and then create a bond due to the transference of electrons from one atom to other. This means, this type of bond occurs between an atom that is positively charged and one that is negatively charged, therefore, the two particles that can form an ionic bond are "A positive calcium ion and a negative oxygen ion" because these two have opposite charges (one is positively charged and one is negatively charged) and therefore electrons can be transferred from one atom to another forming an ionic bond.

What allows transgenic salmon to grow in the winter months?

Nitella [24]

Answer:

An aquaculture company called AquaBounty Farms has produced the first transgenic animal intended for human consumption: Atlantic salmon with two donor genes from other fish. The donated genes keep the transgenic salmon growing year-round, instead of taking a winter break, so they reach adult size faster than normal.

If He gas has an average kinetic energy of 4310 J/mol under certain conditions, what is the root mean square speed of O2 gas mol

Free_Kalibri [48]

Answer:

The root mean square speed of O2 gas molecules is

519.01 m/s

Explanation:

The root mean square velocity :

$v_{rms}=\sqrt{\frac{3RT}{M}}$

$K.E_{avg}=\frac{3}{2}RT$

$K.E =\frac{1}{2}mv_{rms}^{2}$

Molar mass , M

For He = 4 g/mol

For O2 = 2 x 16 = 32 g/mol

O2 = 32/1000 = 0.032 Kg/mol

First calculate the temperature at which the K.E of He is 4310J/mol

K.E of He =

$K.E_{avg}=\frac{3}{2}RT$

$T=\frac{2(K.E)}{3(R)}$

K.E of He = 4310 J/mol

$T=\frac{2(4310J/mol)}{3(8.314J/Kmol)}$

$T=345.60K$

Now , Use Vrms to calculate the velocity of O2

$v_{rms}=\sqrt{\frac{3(8.314J/Kmol)(345.60K)}{0.032Kg/mol}}$

$v_{rms}=\sqrt{\frac{8619.9552}{0.032}}$

$v_{rms}=\sqrt{26935.001}$

$v_{rms}=519.01m/s$

Two conditions are required for cloud formation:cooling of the air and

Lelechka [254]

Answer:

Presence of water molecules

Explanation:

Temperature decreases with an increase in altitude. At sufficiently high altitudes, the air is much colder than the air on the surface of the Earth. Water vapor has a low density and is capable to rise until it gets into a medium with a significantly low temperature and pressure to condense and produce water droplets out of water vapor. Those droplets then form clouds.

The most common mineral in earth's crust is ________, and the second most common mineral is ________.

11111nata11111 [884]

The earth's crust is primarily composed of a mineral named feldspars. Feldspars are the most common mineral by a margin of 30% more than the second most common mineral, quartz. Together, both of these minerals make about 50% of our Earth's crust.
