Answer


<h2>The subduction's zones boundaries are the biggest collision between two tectonic plates. </h2><h2 /><h2>Explanation:</h2><h2 />

A subduction zone is the largest wreck scene on Earth. These lines indicate the crash within two of the planet's tectonic plates. The plates are pieces of crust that slowly move across the planet's cover over millions of years. Where two tectonic plates meet, if one or both of the plates are oceanic lithosphere, a subduction zone will form. An oceanic plate will soak back into the mantle. Remember, oceanic plates are made from mantle material at midocean ranges.

Help! I need help on how to do these problems.
svetlana [45]

Answer:

a. 3; b. 5; c. 10; d. 12

Explanation:

pH is defined as the negative log of the hydronium concentration:

pH = -log[H₃O⁺] (hydronium concentration)

For problems a. and b., HCl and HNO₃ are strong acids. This means that all of the HCl and HNO₃ would ionize, producing hydronium (H₃O⁺) and the conjugate bases Cl⁻ and NO₃⁻ respectively. Further, since all of the strong acid ionizes, 1 x 10⁻³ M H₃O⁺ would be produced for a., and 1.0 x 10⁻⁵ M H₃O⁺ for b. Plugging in your calculator -log[1 x 10⁻³] and -log[1.0 x 10⁻⁵] would equal 3 and 5, respectively.

For problems c. and d. we are given a strong base rather than acid. In this case, we can calculate the pOH:

pOH = -log[OH⁻] (hydroxide concentration)

Strong bases similarly ionize to completion, producing [OH⁻] in the process; 1 x 10⁻⁴ M OH⁻ will be produced for c., and 1.0 x 10⁻² M OH⁻ produced for d. Taking the negative log of the hydroxide concentrations would yield a pOH of 4 for c. and a pOH of 2 for d.

Finally, to find the pH of c. and d., we can take the pOH and subtract it from 14, giving us 10 for c. and 12 for d.

(Subtracting from 14 is assuming we are at 25°C; 14, the sum of pH and pOH, changes at different temperatures.)

Describe the famous experiment related to gravity that Galileo may have performed. Include the results. Also, state whether the
vivado [14]

Answer:

Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time,

How many grams of FeO would be needed to make 234.2 grams of Fe in the chemical reaction 4FeO = Fe3O4 + Fe? Show your work.
Scorpion4ik [409]

The grams  of FeO  that would  be needed to make 234.2 grams  of Fe  is

1204.42 grams


<u><em> calculation</em></u>

4 FeO → Fe₃O₄ +Fe

Step 1: find the  moles  of  fe

moles  =  mass /molar mass

from periodic table the  molar mass of Fe  = 56 g/mol

moles = 234.2 g/56 g/mol = 4.182  moles


Step 2: use  the mole ratio to determine the moles of  FeO

FeO: Fe  is 4:1 therefore the  moles of FeO  =4.182 moles  x4 =16.728  moles


Step 3:   find  the mass of FeO

mass = moles  x molar  mass

The molar mass of FeO = 56 +16 = 72 g /mol

mass  = 16.728 moles  x 72 g/mol= 1204.42 grams
