Answer:

Once the last phosphate group is removed from the ATP molecule by hydrolysis, it will form ADP plus inorganic phosphate. ADP is a lower energy molecule. The release of energy during hydrolysis of ATP can be harnessed by the cell to do work. Living things continuously use ATP but it is renewable and can be recycled.

Mila [183]
<h3>Answer:</h3>

               Option-A (BaTiSi₃O₉)

<h3>Solution:</h3>

Step 1: Calculate Moles of each Element;

                      Moles of Ba  =  %Ba ÷ At.Mass of Ba

                      Moles of Ba  = 33.21 ÷ 137.33

                      Moles of Ba  =  0.241 mol


                      Moles of Ti  =  %Ti ÷ At.Mass of Ti

                      Moles of Ti  = 11.58 ÷ 47.88

                      Moles of Ti  =   0.241 mol


                      Moles of Si  =  %Si ÷ At.Mass of Si

                      Moles of Si  = 20.38 ÷ 28.09

                      Moles of Si  =  0.725 mol


                      Moles of O  =  %O ÷ At.Mass of O

                      Moles of O  = 34.83 ÷ 16.0

                      Moles of O  =  2.176 mol

Step 2: Find out mole ratio and simplify it;

       Ba                            Ti                                Si                          O

     0.241                       0.241                          0.725                    2.176

 0.241/0.241           0.241/0.241                0.725/0.241            2.176/0.241

         1                             1                                    3                           9 

Hence,  Empirical Formula  =  BaTiSi₃O₉

Step 3: Calculating Molecular Formula:

Molecular formula is calculated by using following formula,

                    Molecular Formula  =  n × Empirical Formula  ---- (1)

Also, n is given as,

                     n  =  Molecular Weight / Empirical Formula Weight

Molecular Weight  =  413.44 g.mol⁻¹

Empirical Formula Weight  =  137.33 (Ba) + 47.88(Ti) + 28.09 (Si₃) + 16 (O₉)  =  413.48 g.mol⁻¹

So,

                     n  =  413.44 g.mol⁻¹ ÷ 413.48 g.mol⁻¹

                     n  =  1

Putting Empirical Formula and value of "n" in equation 1,

                    Molecular Formula  = 1 × BaTiSi₃O₉

                   Molecular Formula  =  BaTiSi₃O₉

If you start with 45.0 grams of ethylene and an excess of oxygen, how many grams of carbon dioxide will be produced?A.29 gB.57 g
Vedmedyk [2.9K]

Answer:

D.141 g

Explanation:

Given that:-

Mass of ethylene = 45.0 g

Molar mass of ethylene = 28.05 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{45.0\ g}{28.05\ g/mol}

Moles= 1.60\ mol

According to the reaction below:-

C_2H_4+3O_2\rightarrow 2CO_2+2H_2O

1 mole of ethylene produces 2 moles of carbon dioxide

So,

1.60 mole of ethylene produces 2*1.60 moles of carbon dioxide

Moles of carbon dioxide = 3.2 mol

Molar mass of carbon dioxide = 44.01 g/mol

Mass = Moles*Molar mass = 3.2 mol x 44.01 g/mol = 141 g

<u>D.141 g  of carbon dioxide will be produced</u>

Among the following, which atom is most likely to form an ion with a charge of 2+?
Zigmanuir [339]

Answer:

C. Ca.

Explanation:

The atom loses or gains electrons forming anion or cation to reach stability (fill the outermost shell of the electron levels).

When atom gains electrons forms anions with negative charge.

While, when atom loses electrons forms cations with positive charge.

A. O:

O atom has 8 electrons in its nucleus and gains 2 electrons to reach stability (10 electrons, configuration of Ne).

<em>So, it forms O²⁻.</em>

<em></em>

B. AI:

Al atom has 13 electrons in its nucleus and loses 3 electrons to reach stability (10 electrons, configuration of Ne).

<em>So, it forms Al³⁺.</em>

<em></em>

C. Ca:

Ca atom has 12 electrons in its nucleus and loses 2 electrons to reach stability (10 electrons, configuration of Ne).

<em>So, it forms Ca²⁺.</em>

<em></em>

D. Na:

Na atom has 11 electrons in its nucleus and loses 1 electron to reach stability (10 electrons, configuration of Ne).

<em>So, it forms Na⁺.</em>

<em></em>
