What is Jadi? is it goat? what language is Jadi?
Answer:
Because carbon has one more proton than boron. Carbon has six and Boron has five.
Explanation:
Because it has more subatomic particles. It has one more proton, one more neutron (usually), and one more electron than boron.
The specific heat of silver is calculated as below
Q(heat) = M(mass) xC(specific heat capacity)
Q= 42.8 j/c
M=181 g
C=?
by making C the subject of the formula
C= Q/M
C= 42.8 j/c/181 g =0.236j/g/c
Answer:
No, it does not follow
Explanation:
The law of consevation of matter states that matter can neither be created nor destroyed. Hence, in a closed system involving a physical or chemical reaction, the amount of matter (mass) present in the reactants must equate the amount of matter in the products.
i.e. mass of reactants = mass of products
In the chemical reaction in the image, sodium reacts with hydrogen chloride (reactants) to give sodium chloride and hydrogen gas (products). That is,
Na(s) + HCl(aq) ------> NaCl(aq) + H2(g)
According to the image, the mass of Na= 14.25g, HCl= 9.50g, {NaCl + H2} = 22.98g
The mass of the reactants is 14.25+9.50= 23.75g
Mass of products= 22.98g
The mass of reactants and products are not equal and hence, does not follow the law of conservation of matter.
