Answer:
There are 70 grams of KOH
Explanation:
First, we calculate the weight of 1 mol of KOH:
Weight 1 mol KOH: Weight K + Weight 0 + Weight H= 39g+ 1g+ 16g= 56 g/mol
1 mol-------56 g KOH
1,25 mol----x= (1,25 molx56 g KOH)/1 mol= <em>70 g KOH</em>
I believe it's Hirsutism, maybe list options if there are any next time! :)
Answer:
Yes it does contain thermal energy.
Explanation:
Cold objects have SOME thermal energy because the particles of all matter are in constant random motion.
Miller collected several organic compounds, both simple (such as formaldehyde) and complex (such as hydrocarbons), commonly found in organisms.
Though his methodology is not undisputed, his results support the concept that abiotic synthesis of organic compounds could have been an early stage in the origin of life.
From the samples collected for chemical analysis, Miller identified a variety of organic molecules that are common in organisms. These included simple compounds, such as formaldehyde (CH2O) and hydrogen cyanide (HCN), and more complex molecules, such as amino acids and long chains of carbon and hydrogen known as hydrocarbons. Miller concluded that organic molecules, a first step in the origin of life, may have been synthesized abiotically on the early Earth.

Answer:
Yes. The two elements can combine to form different compounds.
Explanation:
Two elements can combine at different ratios.
Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.
There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.
