Answer:

As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.

An acorn falls from a tree and accelerates at 9.8 m/s2. It hits the ground in 0.67 s. What is the speed of the acorn when it hit

ivolga24 [154]

Acceleration means that while it's falling, its speed will increase by 9.8 m/s
every second. That's the acceleration of everything that falls near the Earth's
surface, no matter how heavy or light the object is.

In 0.67 seconds, then, the speed of the acorn increases from zero to

(0.67 x 9.8) = <u>6.57 m/s</u> .

Complete and balance the precipitation reactions. Include physical states. Refer to the solubility rules as necessary. precipita

Tcecarenko [31]

The balanced chemical reactions are:

$AgNO{_3}(aq) \ + \ NaCl(aq) \rightarrow \ AgCl(s) \ + NaNO_{3}(aq)\\2K_{3}PO_{4}(aq) \ + 3MgCl_{2}(aq) \rightarrow \ 6KCl(aq) \ + Mg_{3}(PO_{4})_{2}(s)$

Further Explanation:

The following reactions will undergo double displacement where the metal cations in each compound are exchanged and form new products.

For reaction 1, the compounds involved are nitrates and chlorides. To determine the states of the products, the solubility rules for nitrates and chlorides must be followed:

All nitrates are generally soluble.
Chlorides are generally soluble except AgCl, PbCl2, and Hg2Cl2.

Therefore, the products will have the following characteristics:

silver chloride (AgCl) is insoluble
sodium nitrate (NaNO3) is soluble

For reaction 2, the compounds involved are phosphates and chlorides. The solubility rules for phosphates and chlorides are as follows:

Phosphates are generally insoluble except for Group 1 phosphates.
Chlorides are generally soluble except for AgCl, PbCl2, and Hg2Cl2.

Hence, the products of the second reaction will have the following characteristics:

potassium chloride (KCl) is soluble
magnesium phosphate is insoluble

Insoluble substances are denoted by the symbols (s) in a chemical equation. The soluble substances are denoted as <em>(aq).</em>

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase ( PDH ) complex.

Nostrana [21]

Answer:

The statements that correctly describes pyruvate dehydrogenase includes:

- Several copies each of E 1 and E 3 surround E 2.

-A regulatory kinase and phosphatase are part of the mammalian PDH complex.

-E 2 contains three domains.

Explanation:

Pyruvate dehydrogenase is a hydrolase key enzyme in glucose metabolism which converts pyruvate to acetyl- ChoA. It also forms a complex that catalyzes an irreversible reaction that is the entry point of pyruvate into the TCA cycle. Pyruvate dehydrogenase complex contains E1, E2 and E3 enzymes that transform pyruvate, NAD+, coenzyme A into acetyl-CoA, CO2, and NADH. Also, A regulatory kinase and phosphatase are part of the mammalian PDH complex and E 2 contains three domains.
