Answer: -
Rimmed steel does not contain nickel.
Explanation: -
Rimmed steel is a deoxidised low carbon steel. Deoxidation leads to formation of rims in the iron.
Carbon, sulfur and phosphorus is present in rimmed steel. The concentrations of these vary from the outer rim to the inner rim. It is not as tough as other steel.
Hence it is primarily used for products where a lot of bending is required. Thus Rimmed steel does not contain nickel.
Answer:
B) 101,025
Explanation:
1000g * 0.449 J/g Celsius * 225 Celsius = 101,025
I got 225C from 250C - 25C

4.0
i think it has something to do with molar ratios and finding the limiting reactant
4.0 mol NO * 2 mol NO2/2 mol NO = 4.0 moles of NO2
4.0 mol O2 * 2 mol NO2/1 mol O2 = 8.0 moles of NO2
so the limiting reactant (the reactant that runs out the quickest leaving an excess) is NO
once the limiting reactant is found, we can use that data for that substance to calculate the amount of product
4.0 mol NO * 2 mol NO2/2 mole NO = 4.0 moles of NO2
<span>The question says,'salt is the product formed by a reaction in which .............atoms of an acid are replaced by the atoms of a metal. The correct answer is hydrogen atoms. Salts are formed as a result of the hydrogen ions in the acid been replaced by metal ions or other positive ions in the base.</span>
