Answer:

the correct answer B. carboxylic acid

Explanation:

carboxylic acid, any of a class of organic compounds in which a carbon (C) atom is bonded to an oxygen (O) atom by a double bond and to a hydroxyl group (―OH) by a single bond. A fourth bond links the carbon atom to a hydrogen (H) atom or to some other univalent combining group.

Evgesh-ka [11]
Answer is: <span>negative beta decay.
</span>
Nuclear reaction: ¹⁴C → ¹⁴N + e⁻ + νe (electron antineutrino).
<span>In beta minus decay (atomic number Z is increased by one, from 6 in carbon to 7 in nitrogen) neutron is converted to a proton and an electron and an electron antineutrino.
</span><span>Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.</span>

<u>Answer:</u> The tree was burned 16846.4 years ago to make the ancient charcoal

<u>Explanation:</u>

The equation used to calculate rate constant from given half life for first order kinetics:

t_{1/2}=\frac{0.693}{k}

where,

t_{1/2} = half life of the reaction = 5715 years

Putting values in above equation, we get:

k=\frac{0.693}{5715yrs}=1.21\times 10^{-4}yrs^{-1}

Rate law expression for first order kinetics is given by the equation:

k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}

where,

k = rate constant  = 1.21\times 10^{-4}yr^{-1}

t = time taken for decay process = ? yr

[A_o] = initial amount of the sample = 100 grams

[A] = amount left after decay process =  13 grams

Putting values in above equation, we get:

1.21\times 10^{-4}=\frac{2.303}{t}\log\frac{100}{13}\\\\t=16864.4yrs

Hence, the tree was burned 16846.4 years ago to make the ancient charcoal

Why are weather satellites useful in areas that are affected by hurricanes?
snow_lady [41]

Answer:

Since they are in a geostationary orbit, the GOES satellites provide continuous monitoring of the Earth's surface. They are able to constantly monitor the life cycle of significant weather such as hurricanes, tornadoes, flash floods, and hail storms.
