Answer:
im rly good with this stuff and i'm working on genetics and phenotypes and stuff.
Explanation:
information that determines your traits basically from your parents
We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.
Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J
Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).
Answer: a) 90.5g
b) 33.6 L
Explanation:-
Molar mass of tyrosine 
= 181 g/mol
According to Avogadro's law, 1 mole of every substance weighs equal to its molar mass.
1 mole of tyrosine weighs = 181 g/mol
0.5 moles of tyrosine weigh 
b) According to Avogadro's law, 1 mole of an ideal gas occupies 22.4 Liters at Standard conditions of temperature and pressure (STP).
1 mole of gas at STP occupy = 22.4 L
1.5 moles of gas at STP occupy =
Because as u go across groups the more reactive it is due to the ability of electrons to be given or taken away
Answer:
Oxygen gas
Explanation:
It is a pure element. The rest are compounds made up of two or more elements. For eg silicon dioxide is made of silicon and oxygen.
