Explanation:
The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).
Answer:
The outside temperature is -45.8°C
Explanation:
When a gas keeps on constant its moles and its pressure, we can assume that volume will be increased or decreased as the T° (absolute T° in K).
V1 / T1 = V2 / T2
2.95L/298K = 2.25L / T2
(2.95L/298K ) . T2 = 2.25L
T2 = 2.25L . 298K / 2.95L
T2 = 227.2K
T°K - 273 = T°C
227.2K - 273 = -45.8°C
Answer:
2.29 g of N2
Explanation:
We have to start with the <u>chemical reaction</u>:

The next step is to <u>balance the reaction</u>:

We can continue with the <u>mol calculation</u> using the molar mass of
(65 g/mol), so:

Now, with the<u> molar ratio</u> between
and
we can <u>calculate the moles</u> of
(2:3), so:
With the molar mass of
we can <u>calculate the grams</u>:
I hope it helps!
Answer:
Covalent Bond
Explanation:
In the diagram Carbon and each of the 4 Hydrogens are sharing electrons. They are also both non metals. Both of these are characteristics of Covalent Bonds.
