Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.

an effective hot pack salt can release 5850 j of heat to the surroundings. how many grams of licl are needed to release this amo
Montano1993 [528]

4.01 grams of Licl are needed to release this amount of heat

<h3>What does one gram weigh?</h3>

The gram is a unit of mass in the International System of Units (SI) that is equal to one thousandth of a kilogram. It was originally known as the gramme. Gram. This pen cap weighs around one gram. A weight scale like this one may provide a precise mass readout for many different things.

Mass of Licl required to release 5850J of heat to the surroundings.

Let x g Licl required.

Then x g ×∆H = 5850J

x g × 1.46 × 10³ = 5850

x = 5850/ 1.46 × 10³

x = 4.0068

so 4.01g Licl required.

The normal range of the pH of blood is between 7.35 and 7.45; variations beyond this range have significant health implications.
patriot [66]

Answer:

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.

Explanation:

To calculate the pH of the solution, we use the equation:

pH=-\log[H^+]

We are given:

1) pH = 7.35

Putting values in above equation, we get:

7.35=-\log[H^+]

[H^+]=4.467\times 10^{-8} M\approx 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

2) pH = 7.45

Putting values in above equation, we get:

7.45=-\log[H^+]

[H^+]=3.548\times 10^{-8}M \approx 3.6\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.

An unknown compound, B, has the molecular formula C7H12. On catalytic hydrogenation 1 mol of B absorbs 2 mol of hydrogen and yie
Ne4ueva [31]

Answer:

5-methylhex-1-yne//5-methylhex-2-yne//2-methylhex-3-yne

Explanation:

We have to start with the information on the <u>IR spectrum</u>. The signal at 3300 is due to a <u>C-H bend sp carbon</u> and the signal in 2200 is due to the <u>stretch carbon-carbon</u>. Therefore we will have an alkyne. Now if we have 2-methylhexane as the product of hydrogenation we have <u>several options to put the triple bond</u>. Between carbons 1 and 2 (5-methylhex-1-yne), between carbons 2 and 3 (5-methylhex-2-yne) and between carbons 3 and 4 (2-methylhex-3-yne). On carbon 5 we have a tertiary carbon therefore we dont have any other options.

See figure 1

I hope it helps!

Answer:

A

Explanation:

Hot air is less dense therefore it rises. Cold air is more closely packed therefore it is more dense. Less dense things rise while more dense things sink.
