Answer:

Mark has a speed of 6 MPS (Miles Per Hour)

Explanation:

It took mark 2 hours to ride his bike to his grandma's house, which was 12 miles away. I divided 2 by 12 and got 6. Remember this: mph = miles away ÷ time.

Distance divided by time
So 12/2 So he would be going 6mph

what is the net yield of atp when palmitate (c16) is completely oxidized via the β-oxidation pathway? express answer as whole nu
wariber [46]

When palmitate (C16) completely oxidized, net yield is 129 ATP.

There are 7 β-oxidation cycles for palmitate to completely oxidazed.

One β-oxidation (beta-oxidation) cycle produces 1 NADH, 1 FADH2, and 1 acetyl CoA (sea the picture below).

For 7 cycles: 7 NADH, 7 FADH2,  and 8 acetyl CoA.

NADH and FADH2 enter Electron Transport System (ETS) cycle to generate 3ATP and 2ATP respectively.

Acetyl CoA enter into tricarboxylic acid cycle (TCA) and each CoA gives 12 ATP.

7 NADH = 7 x 3 = 21 ATP

7 FADH2 = 7 x 2 = 14 ATP

8 acetyl-CoA = 8 x 12 = 96 ATP

Net yield of ATP = 21 ATP + 14 ATP + 96 ATP - 2 ATP (used during conversion of palmitic acid into palmitoyl CoA)

Net yield of ATP = 129 ATP

snow_lady [41]

Answer:

0.31 mol K x 39.1 grams K/ 1 mol k = 12.1 g

Explanation:

molar mass of K: 39.1

In order to find the mass in 0.31 mol of K, you must covert moles to grams. In one mole of Potassium there is 39.1 grams.

A noble gas is placed in a 10.0 liter container. the noble gas has a mass of 25.25 g, the pressure is 3.05 atm, and the temperat
valina [46]

The problem can be solved using Ideal Gas Equation.

The equation is given below.

PV= nRT

Step 1 : Calculate moles of the gas (n)

Where P = pressure of the gas in atm = 3.05 atm

V = Volume of the gas in Liters = 10.0 L

n = number of moles of the gas

R = Gas constant = 0.08206 L-atm/mol-K

T = Temperature of the gas in Kelvin

To convert T from Celsius to Kelvin unit, we add 273

Hence we have T = 24 + 273 = 297 K

Let us plug in the above values in ideal gas equation

(3.05 atm) ( 10.0 L) = n (0.08206 L.atm/mol.K) ( 297 K)

n = \frac{(3.05atm) (10.0L)}{(0.08206 L-atm/mol) (297)} ... Unit K gets cancelled

n = 1.25 mol

Number of moles of gas are 1.25

Step 2 : Find molar mass using mol value

Mole and molar mass can be related to each other by the following expression

Mole = \frac{Mass (grams)}{Molar mass}

The mass of the gas is given as 25.25 g

moles (n) = 1.25 mol

After plugging the values we get,

1.25 mol = \frac{25.25g}{Molar mass}

Molar mass = \frac{25.25g}{1.25mol}

Molar mass = 20.2g/mol

Molar mass of the gas is 20.2 /mol

Step 3 : Find identity of the gas using periodic table

From the periodic table , we can see that noble gas Neon has molar mass 20.18g/mol .

Hence the given gas is Neon which is represented by the symbol is "Ne"
