I ve been thinking about it for a long time, who can answer, it s actually quite simple to send poin

I suggest you study some philosophy. At the same time, this kind of question is a bit boring.

If it's absolute time that doesn't move, you don't move.

If it's relative to time that doesn't move, you're all moving.

Above! By the way, you just say that you have speed, and speed cannot exist without time. So you're not thinking enough.

After reading it, I feel that what is being said downstairs is a concept of relative time. I don't know how to express the concept of absolute time, but I guess it's something between existence and death.

Suppose D is telling the truth, then A is not B or C is doing a lie, and it is true!

Suppose C is telling the truth, then D did it, and everyone else is telling a lie!

If B is telling the truth, then B did it, then A says that either B is doing it, and C is also false, which is a contradiction.

Assuming that A is telling the truth, then B or C is true.

According to the above analysis, it is ACD that did it.

The words of A and C are contradictory, so one must be true and the other false.

If A is true then B is also true, so it can't be, so A is false and C is true, and therefore D is dry.

Once upon a time there was a body, and it had many members, hands, mouth, nose, teeth, legs, and so on. They often do things together. One day, while the eyes were still sleeping, the nose smelled something on the table, "Ah!

It's like roast duck! ”。At this moment, the mouth quickly ate a piece without saying a word.

Well, yes, it tastes like roast chicken. ”

The eyes were too sleepy to open, so they let their hands touch the food. The nose asked, "What does it feel like?" He washed himself by hand and touched the food, "It felt like a piece of meat." Hand replied. "It's meat, so can it be eaten? Eyes asked.

Yes! My stomach hurts! It's bad!

Stomach shouting. "I have to go to the toilet. He quickly ran to the toilet.

That's when the ears hear what they don't want to hear. "This piece of food is bad, it's full of flies! A woman said.

Ah, the mouth has eaten something bad", said the eye, "he must be more careful next time, or we will all suffer!" ”

caco3+2hcl==cacl2+h2o+co2↑100 44

125*80% x

The column proportional solution yields x==44g

A: But it's 44 grams of carbon dioxide.

m（caco3）=125*80%=100

The amount of calcium carbonate is 1mol

So 1mol of carbon dioxide is generated.

So 44g will be generated

First, calculate the mass of calcium carbonate 125g*80%=100g with carbon dioxide x

caco3+2hcl=cacl2+h20+co2↑100 44

100g x

100/100g=44/x

x =44g

Tomatoes 315 kg Turnips weigh 4 times more than tomatoes Question: How many kilograms less are tomatoes than turnips? Solution: (315*4)-315=945 (kg).
