PIT_PIT [208]

Answer:

Explanation:

1. Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3

2. FeSO4 + 2 NaOH = Fe(OH)2 + Na2SO4

3. Fe(NO3)3 + 3 NaOH = Fe(OH)3 + 3 NaNO3

For the second part of 3 since it tells us NaOH is excess we dont care about it. We use our balanced equation 3 to get the correct molar ratios to solve this.

1.5mol Fe(NO3)3 x 3mol NaNO3/1mol Fe(NO3)3 x 84.99gNaNO3/1molNaNO3

= 382.455g NaNO3

allsm [11]

Answer: <u>Hydrogen.</u>

Explanation: <u>One problem with fuel-cell cars is that hydrogen gas is not readily available in pure form.</u> Fuel cell vehicles use hydrogen gas to power an electric motor. Unlike conventional vehicles which run on gasoline or diesel, fuel cell cars and trucks combine hydrogen and oxygen to produce electricity, which runs a motor. Hope this helps ^-^.

Given the DNA template strand 3\' AACAGACAG 5\', write the amino acid sequence in the N-terminal to C-terminal direction. Use th
Stolb23 [73]

Answer: The amino acid sequence is Leu-Ser-Val

Explanation: To produce amino acids, the DNA has to "transform" itself into a RNA by a process called Transcription. In this process, part of the DNA is transcribed into a similar RNA. The RNA produced undergoes another process, called Translation. From it, the sequence is decoded to a specific polypetide, as shown in this case. In the Translation, each 3 bases corresnpond to 1 amino acid. Because of it, the sequence above has 3 amino acids.

The N-terminal and C-terminal relates to the part where the sequence start to be read and the end of the process. Normally, the sequence starts at the 5', which correspond to the N-terminal and finishes at the 3', which matches the C-terminal. So in this example, the DNA template read 5\'GACAGACAA 3\'.
