Answer:
Li2O+H2O---->(2)LiOH
Explanation:
you have to balance the equation and not all the blanks have to be filled all the time but if it makes it easier for you in the first 2 question marks you can put a 1 which isnt necessary but if ur a visual person it will help.
hope this helps im litterally learning the same thing as u lol
Answer:
1,1,2
Explanation:
this was correct for me, if it wasnt correct check if youre on the right question
b. consumption resource.
c. renewable resource.
d. nonrenewable resource
copper is not a stone, copper is not a consumption resource, and copper is not renewable, that means that :
d. nonrenewable resource
Explanation:
A nonrenewable source is a source of economic value that cannot be immediately displaced by natural means on a level equal to its destruction. Most fossil fuels, such as oil, natural gas, and coal are estimated nonrenewable resources in that their use is not sustainable because their production takes billions of years.
Copper is an example of a(n) (D), nonrenewable resource which are resources that can be replenished naturally.
Copper is a nonrenewable resource because it cannot be created or replaced once it is used up. Copper is a metal that is used in a variety of products, including electrical wiring, plumbing, and jewelry.
Gemstones are naturally occurring minerals that are prized for their beauty and rarity. They are considered to be a type of nonrenewable resource, although they can be recycled.
Consumption resources are resources that are used up quickly and need to be replaced frequently. Renewable resources are resources that can be replenished naturally.
So the answer is d. nonrenewable resource.

The part of the nervoussystem is a gray, wrinkled organ consist of millions of neurons is the brain. Therefore, option B is correct.
The nervous system is made up of the brain, spinal cord, and a sophisticated network of nerves. By this system, the body and the brain are transmitted. The brain performs every physical function. The spinal cord moves the brain through the back.
The brain and spinal volume unit are the organs of the central nauseous system. Since they are so vitally important, the brain and spinal cord, which are located in the dorsal body cavity, are protected by a bone shell.
Your entire body is controlled by your brain. Even when you sleep, it controls practically all of your behaviors and runs the show. For something the size of a wrinkled sponge of grey, it was really bad.
Thus, option B is correct.

B. less than 0.5 grams of sugar per serving.
C. less than 5 milligrams of sugar per serving.
D. less than 2 milligrams of sugar per serving.
Answer:
A food product claiming to be sugar free contains less than 10 grams of sugar per serving.
Explanation:
There are several sugars, such as lactose (milk), fructose (fruits and honey), maltose (beer), sucrose (table sugar), among others. These can be classified into intrinsic sugar, that is the sugar that is part of the composition of foods such as milk (lactose), vegetables or fruits (fructose) and free sugars, which are those added by manufacturers, consumers or cooks. This last classification includes sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
The main difference between them is that eating a large amount of food containing free or added sugar causes a metabolic reaction that increases the risk of being overweight or obese, and of developing diabetes, gout, ulcerative colitis, vascular diseases and caries. However, the consumption of intrinsic sugars does not pose a health risk. Therefore, the recommendation of the World Health Organization is that the daily consumption of free sugars should be reduced to less than 10% of the total caloric intake, that is, to a maximum of 25g of free sugars per day.
b. Zero
c. No right choice.
a. Negative
Explanation:
We have to look at its oxidation (burning, explosion) of TNT:
4 C₇H₅N₃O₆ + 21 O₂ → 28 CO₂ + 10 H₂O + 6 N₂ + heat
So trinitrotoluene need more oxygen atoms that is have to be fully oxidized so the oxygen balance will be negative.
An empirical formula with which you calculate the oxygen balance percent (OB %) is:
OB % = (-1600 / molecular wight) × [2X + (Y/2) + M - Z)
were
X = number of carbon atoms
Y = number of hydrogen atoms
M = number of metal atoms
Z = number of oxygen atoms
For TNT:
OB % = (-1600 / 227.13) × [2×7 + (5/2) + 0 - 6)
OB % = -73.97 %
So the oxygen balance percent is negative.
