For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun's rays strike the surface more directly, giving us warmer temperatures.

How are energy storage molecules affected if there is LESS carbon dioxide?

kipiarov [429]

Answer:

When there is less carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available for producers making energy storage molecules. When there is more sunlight, producers can make more energy storage molecules from the carbon in carbon dioxide.

Hope this helps.

A particular reactant decomposes with a half‑life of 109 s when its initial concentration is 0.280 M. The same reactant decompos

Sophie [7]

Answer:

The order of reaction is 2.

Rate constant is 0.0328 (M s)⁻¹

Explanation:

The rate of a reaction is inversely proportional to the time taken for the reaction.

As we are decreasing the concentration of the reactant the half life is increasing.

a) For zero order reaction: the half life is directly proportional to initial concentration of reactant

b) for first order reaction: the half life is independent of the initial concentration.

c) higher order reaction: The relation between half life and rate of reaction is:

Rate = $\frac{1}{k[A_{0}]^{(n-1)}}$

Half life = $K\frac{1}{[A_{0}]^{(n-1)} }$

$\frac{(halflife_{1})}{(halflife_{2})}=\frac{[A_{2}]^{(n-1)}}{[A_{1}]^{(n-1)} }$

where n = order of reaction

Putting values

$\frac{109}{231}=\frac{[0.132]^{(n-1)}}{[0.280]^{(n-1)}}$

$0.472=(0.472)^{(n-1)}$

Hence n = 2

$halflife=\frac{1}{k[A_{0}]}$

Putting values

$231=\frac{1}{K(0.132)}$

K = 0.0328

What type of map projection makes plotting travel by airplane the easiest? I know it's azimuthal maps but why

KatRina [158]

Answer:

Explanation:

Azimuthal maps projection is the easiest for plotting travel by airplane because Azimuthal maps make the UV plane to be tangent to the globe and it's make the directions from the center of projections to be correct and accurate to any other points , likewise circles are also projected directly to the straight lines on the plane. And this is because Any line that is normally drawn through the tangent point give distance correctly and accurately.
