Explanation:

........

The pair of elements which will form covalent bonds with each other are Si (Silicon) and N (Nitrogen). Hence the correct option is (B).

A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.

These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Silicon and nitrogen forms strong covalent bond . This stable covalently bonded material does not readily sinter and cannot be heated over 1850⁰C as it dissociates into silicon and nitrogen.

Therefore, The pair of elements which will form covalent bonds with each other are Si (Silicon) and N (Nitrogen). Hence the correct option is (B).

I Would Determine Mass,Volume And Weight

Answer:

40.06 amu.

Explanation:

From the question given above, the following data were obtained:

Isotope A (K-39)

Mass of A = 39 amu

Abundance of A = 23%

Isotope B (K-40)

Mass of B = 40 amu

Abundance of B = 48%

Isotope C (K-41)

Mass of C = 41 amu

Abundance of C = 100 – (23 + 48)

Abundance of C = 100 – 71

Abundance of C = 29%

Average mass =?

Average mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(39 × 23)/100] + [(40 × 48)/100] + [(41 × 29)/100]

= 8.97 + 19.2 + 11.89

= 40.06 amu

Thus, the average mass of potassium is 40.06 amu

Answer: It’s Lower

What can you say about the pH of a carbonic acid solution compared to that of a sulfuric acid soloution with the same contention: Strong acids dissociate fully in water to produce the maximum number of [tex]H^{+}[/tex]ions. The pH levels of strong acids are smaller than those of low acids, which is why the reactions rates for strong acids are greater than the reactions of weak acids with products like metals, metal carbonates, etc. Meaning The pH Level is lower.

Answer:

3)The formula for speed is

speed=distance ÷ time

distance is in metres (m)

and time is in seconds (s),

so the units will be in metres per second (m/s).

4)to solve for distance use the formula for distance d = st, or distance equals speed times time. ... You can use the equivalent formula d = rt which means distance equals rate times time. distance = rate x time.

5)To solve for time use the formula for time,

t = d/s which means time equals distance divided by speed.

6)The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour.
