Ionic compounds form when a metal and nonmetal bond, as the metal loses its valence electrons which the nonmetal gains, resulting in an ionic bond. Covalent compounds form when two nonmetals bond, as they tend to share electrons allowing them to complete their valence shells resulting in a covalent bond.
The formation of ionic and covalent compounds depends on the elements involved and their properties. Metals, generally, have few valence (outer shell) electrons, while nonmetals have more. When a metal and nonmetal bond, the metal tends to lose its valence electrons, becoming a positively charged ion or cation, and the nonmetal gains these electrons, becoming a negatively charged ion or anion. This transfer of electrons results in an ionic bond.
On the other hand, when two nonmetals bond, they tend to share electrons because neither atom can completely overcome the other's attraction for electrons. These shared electrons allow them to complete their valence shells. This sharing of electrons results in a covalent bond.

Answer : The correct option is, Cleavage.
Explanation :
Mica : It is silicate mineral and also known as sheet silicate because they form in different layers.
Cleavage : It is a type of mineral properties. It describes how a crystal breaks when stress apply to the crystal and breaks into a particular plane.
If the mica breaks due to stress and breaks into thin sheet, that means the mineral has cleavage.
Therefore, the correct answer is, Cleavage.
Answer:
Cleavage
Explanation:
the correct answer is 7897.0 Joules
Outliers existing in a data set will have the greatest impact on :
option: A is the correct answer.
A. The mean.
We know that an outlier is a data value or the data point that stands out of the rest of the data points of the set i.e. it either attains a too high or too low value as compared to other data points.
Hence, the outlier will effect the mean of the data set.
( Since, when a too low value is present in the set then after removing that value the mean of remaining elements or data points will increase after removing the outlier.
For example if we have data set as:
1 30 34 39 41 45
Then mean of the set is:
and on removing 1 from the set we get:
Hence, we see that the mean is increased.
Similarly, if there is a data value which is too high then after removing that element the mean of the remaining data points will decrease )
Answer : The partial pressure of is, 66 Kpa
Solution :
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
where,
= total partial pressure = 282 Kpa
= partial pressure of nitrogen = ?
= partial pressure of oxygen = 110 Kpa
= partial pressure of hydrogen = 106 Kpa
Now put all the given values is expression, we get the partial pressure of the nitrogen gas.
Therefore, the partial pressure of is, 66 Kpa

Answer:
Conversion gives 42,107 km in total
Explanation:
A marathon covers 26 miles and 285 yards.
If 1 kilometer is 0.6214 miles, then how many kilometers are 26 miles, then:
1 km = 0.6214 miles
X = 26 miles
X = 41,841 km
Now if 1 yard is 36 inches, how many inches is 285 yards?
1 yard = 36 inches
285 yards = X
X = 10260 inches
If an inch is equal to 2.54 cm, how many centimeters are 10260 inches?
1 inch = 2.54 cm
10260 cm = X
X = 26060.4 cm
And 26060.4 cm is 0.260604 km
Finally, the sum of the distance would be:
41.841 km + 0.260604 km = 42.107 km
