Answer:

Proxima Centuri is 9 orders of magnitude further from New York compared to Perth

Explanation:

Distance of Proxima Centuri to New York = 4 × 10^16 meters

Distance of Proxima Centuri to Perth = 11000 miles

Since 1 mile = 1609 meters, distance to Perth in meters = 11000 × 1609

Distance to Perth = 17699000 = 1.7699 × 10^7 meters

Order of magnitude of the distances of Proxima Centuri to New York and Perth = 10^16/10^7

Order of magnitude = 10^9

Therefore, Proxima Centuri is 9 orders of magnitude further from New York compared to Perth.

amm1812

Other natural material such as clay, wood, and stones can be changed into art.

Clay is pliable and is very easy to be molded into different shapes and sizes.

Wood can easily carved into different shapes, also different patterns can be easily etched on wood.

Stones of different variety and from different geological sources are painstakingly converted into statues or portraits of different life forms and scenery.

Which of these pairs of elements would be most
allsm [11]

Answer:

The correct answer is  B) Cl and Mg

Explanation:

An ionic bond is produced by the union of a cation and an anion. In this case, Mg would be the cation and Cl the anion. They will form the compound Magnesium Chloride (MgCl2):

Mg + Cl2 ----> MgCl2

Mg belongs to group 2 of the periodic table, that is, it has two valence electrons. In the case of Cl, it is in group 7 and has seven valence electrons (requires one electron to complete the octet).

HELP! I NEED THIS ANSWERED ASAP!!!
stealth61 [152]

Answer:

The rate of reaction will maintain constant

Explanation:

Rate of reaction is proportionate to rate constant x [A] ^2 x [B]. This means that the order of reaction with respect to C is 0 as it does not affect the rate of reaction as seen in the rate equation.

Essentially, order of reaction with respect to C is [C] ^0

Hence if [C] triples and becomes [3C]^0, the result will still be 1 as anything to the power of 0 is 1.

Therefore, the answer is that the rate of reaction will remain constant.
