How many grams of water would require 2200 joules of heat to raise it’s temperature from 34 degrees Celsius to 100 degrees celsi
Arada [10]

Answer:

Mass, m = 7.97 grams

Explanation:

We have,

Initial temperature was 34 degrees Celsius

Heat produced in it is 100 calories of heat

The specific heat capacity of water is 4.18 J/g °C

The heat produced due to change in temperature is given by :

Q=mc(T_f-T_i)

m is mass of water in grams

m=\dfrac{Q}{c(T_f-T_i)}\\\\m=\dfrac{2200}{4.18\times (100-34)}\\\\m=7.97\ g

So, 7.97 grams of water is required to produce heat of 2200 joules.

a sample of CO2 occupies a volume of 280ml at a pressure of 1.3 atm and a temperature of 18 degrees celsius, what volume will th
monitta

We can calculate the new volume of the gas using the Combined Gas Law:

(P1 x V1) / T1 = (P2 x V2) / T2

The initial volume, pressure, and temperature were 280 mL, 1.3 atm, and 291.15 K (changing the temperature into Kelvin is necessary), and the final volume, pressure, and temperature is V2, 3.0 atm, and 308.15 K. Plugging these values in and solving, we find that:

(P1 x V1) / T1 = (P2 x V2) / T2

(1.3 atm x 280 mL) / 291.15 K = (3.0 atm x V2) / 308.15 K

V2 = 128.42 mL

This makes sense considering the conditions, a small increase in temperature would make the gas expand but a significant increase in the pressure would cause the volume to decrease.

Hope this helps!

1.) Calculation: If 9.02 x 1024 particles of vinegar (HC2H3O2)HC2H3O2) are added to 16.5 moles of eggshell (CaCO3) and 6.35 mole
blsea [12.9K]

The theoretical yield of acetate is 2607 g. The actual yield of acetate is 1066.8 g. The percentage yield of acetate is 41%.

If 1 mole of vinegar contains 6.02  x 10^23 particles

x moles of vinegar contains 9.02 x 10^24 particles

x = 1 mole x 9.02 x 10^24 /6.02 x 10^23

x = 15 moles of vinegar

The reaction is as follows;

2HC2H3O2 + CaCO3 -----> Ca(C2H3O2)2 + H2O + CO2

Since 2 moles of vinegar reacts with 1 mole of carbonate

x moles of vinegar reacts with 16.5 moles of carbonate

x =  2 moles x 16.5 moles/ 1 mole

x = 33 moles of vinegar

We can see that the vinegar is the reactant in excess hence the carbonate is the limiting reactant.

Theoretical yield = 16.5 moles x 158 g/mol = 2607 g

Actual yield = 6.35 moles  x 158 g/mol = 1066.8 g

Percent yield = 1066.8 g/2607 g × 100/1

= 41%

How to make vape oil from scratch for a vape pen
Julli [10]
If you’ve been vaping for a while now, you may be craving some new vape juice flavors to try with your favorite RDA, RTA, or Box Mod.

You might find that ordering large batches of your all day vape juice flavors can prove a bit on the expensive side, particularly if your tastes run toward the premium e juice priced at over $20 per bottle.

Surely there must be a better way than taking out payday loans to get your hands on that Peanut Butter Crunch-flavored creation you just have to have in your sub-ohm tank?

Fortunately, when you know how to make homemade vape juice it can be a fun and fascinating hobby that has the delightful side effect of saving you loads of cash using cheap vape juice.

Many people hear “diy vape juice” and get visions of a mad scientist in a dank lab constantly flirting with explosion by mixing volatile chemicals while laughing insanely.

The reality is that it’s relatively easy to learn how to make your own vape juice at home, and we’re going to attempt to cover all the facets involved.

Are you interested in making your own e juice?

What is bank?Effect of drug abuse.<br>​
jeyben [28]

- Long term effects

Chronic drug use can alter a person’s brain structure and function, resulting in long-term psychological effects, such as: depression, anxiety, panic disorders, increased aggression, paranoia, hallucinations.

- Cardiovascular disease

Stimulants, such as cocaine and methamphetamines, can damage the heart and blood vessels. The long-term use of these drugs can lead to coronary artery disease, arrhythmia, and heart attack.

- Respiratory problems

Drugs that people smoke or inhale can damage the respiratory system and lead to chronic respiratory infections and diseases. Opioids slow a person’s breathing by binding to specific receptors in the central nervous system that regulate respiration. By depressing a person’s respiration, these drugs can lead to slow breathing or heavy snoring.

- Kidney damage

The kidneys filter excess minerals and waste products from the blood. Heroin, ketamine, and synthetic cannabinoids can cause kidney damage or kidney failure.

- Liver disease

Chronic drug and alcohol use can damage the liver cells, leading to inflammation, scarring, and even liver failure.

- Overdose

Taking too much of a drug or taking multiple drugs together can result in an overdose. According to the Centers for Disease Control and Prevention (CDC), drug overdose caused 67,367 deathsTrusted Source in the United States in 2018. Opioids contributed to nearly 70% of these deaths.

How to get help:

Finding the right treatment program can be a daunting task. Here are a few things to think about when seeking treatment for drug abuse, misuse, or addiction:

consider whether inpatient or outpatient services would be the best fit

find local treatment centers using this resource from the Substance Abuse and Mental Health Services Administration

note that state-run treatment centers and programs can be free of charge

look for programs that use evidence-based treatment strategies
