Answer:
m = 1.3 Kg
Explanation:
according to Specific Heat Formula :
Q = mc∆T
when Q is the heat energy in Joules
m is the mass of water
C is the specific heat its unit J/kg∙K
∆T change in temperature (the final t - the initial t)
by substitution:
Q = 190000 g * 4.184 J/g∘C *78
Q = 62006880 J
when The combustion of 1.0 lb of oil provides 2.2×107J
So lb of oil when Q = 62006880 J = 2.8 Ib
and when 1lb=454g
So 2.8 Ib = 1271.2 g = 1.3 Kg
Explanation:
There will occur a straight line for the curve of Ln[(CH_{3})_{3}CCl] Vs. time. Since, it is a first order reaction therefore, the formula of its half-life will be as follows.
Half-life =
or, k =
=
So, rate of the reaction will be as follows.
Rate =
=
= 0.000473
=
Thus, we can conclude that the instantaneous rate of given reaction is .
Answer: Unalienable means it can not be taken away
Explanation:
The 1st amendment has three unalienable rights.
Answer: The net change in the atoms is the conversion of a neutron to a proton, turning Carbon (6 protons) into Nitrogen (7 protons).
Explanation:
Carbon-14, generated from the atmosphere, has 6 protons and 8 neutrons. That's where the 14 comes from, called the mass number, is the sum of protons and neutrons (6+8=14).
Carbon-14 is radioactive and decays by beta decay. That means one of its neutrons spontaneously turns into a proton, an electron, and a neutrino, according to:
After that, the atom has 7 protons and 7 neutrons, maintaining its mass number but changing its atomic number from 6 to 7, turning into Nitrogen.
