Answer:
The elements in this list are:
Silver, hydrogen, carbon, nitrogen, gold, magnesium, nickel, mercury.
Explanation:
Elements are chemical substances that can be found on the periodic table.
The energy required to heat 40g of water from -7 c to 108 c is
1541000 joules
calculation
Q(heat)= M( mass) x c(specific heat capacity) xdelta t( change in temperature)
M= 40g= 40/1000= 0.04 Kg
C= 335,000 j/kg/c
delta T ( 108 --7= 115 c)
Q is therefore = 0.04 g x 335000 j/kg/c x 115 c = 1541,000 joules
Answer:
c. carbon monoxide
Explanation:
no one bothers to read why anyways so look at the picture
Answer:
it may be electron, atom or ions depend on the nature of the substance and the character of reaction
like :- particles per mole, coulombs per electron
