You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. The only problem is that you do not know what element will form. By your previous calculations you know that you will have 6. 3 moles of product. When it is complete, you weigh it and determine you have 604. 4 grams. What element have you produced?.

Answers

Answer 1

Answer:

molybdenum (Mo)

Explanation:

For this question you need to understand what the concept of molar mass is.

Molar mass is the exact mass by which you will obtain a mol of that specific element. For example the molar mass of H2O is 18g/mol, so it means that in 18 grams of water, you exactly have 6.022x10²³ molecules of water or one mole.

So here you know the number of moles you produce and its conversion to grams. The problem is basically stating that in 604.4 grams of x element you have 6.3 moles of that element.

All you have to do is divide the number of grams by the number of moles:

604.4grams/6.3 moles=95.94 g/moles,

You obtained the molar mass of that X element, and in fact the molar mass corresponds the molecular mass of all elements, that is an information provided by the periodic table. So all you have to do is look for the element with a molecular mass of 95.94 uma or a very close approximate.

Molybdenum has a molecular mass of 95.95. So that's the answer.

Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.

Answers

The sum of the two numbers is equal to 70.

Let the first number be x.Let the second number be y.

In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).

Translating the word problem into an algebraic expression, we have;

Two numbers differ by 8:

[tex]x-y=8[/tex]    ....equation 1.

The product of the two numbers is 713:

[tex]xy=713[/tex]    ....equation 2.

To calculate the sum of the two numbers:

First of all, we would solve for each of the unknown variables (x and y).

From eqn. 1, we have:

[tex]x=8+y[/tex]   ....equation 3.

Substituting eqn. 3 into eqn. 2, we have:

[tex]y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0[/tex]

Solving the quadratic equation by factorization, we have:

[tex]y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0[/tex]

y = -23 or 31.

For the value of x, when y = 31:

[tex]x=8+31[/tex]

x = 39

Now, we can calculate the sum of the two numbers:

[tex]x+y=39+31=70[/tex]

Pauline chasse has just signed a lease agreement with landlord, wayne godbrey to rent a house he owns in delano. The lease states definite beginning (january 1, 2016) and ending (october 30, 2016) dates, and sets forth the rent amount and due dates and all additional property and personal information required in such a lease. Wayne hands a copy to pauline, but she notices that he has not signed it. When she comments about this to him, he tells her that signatures are not necessary since the lease is for less than a year. Which of the following is true of this situation?.

Answers

The correct option that is true as regards Wayne's situation about the lease is;

B; Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

The missing options are;

Under the Statute of Frauds in California,

A) leases of less than one year are not even required to be in writing, and therefore, signatures are not required.

B) Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

C) Leases of less than one year are not required to be in writing; but if there is a written lease, then it must be signed by both the lessee and lessor.

D) Because the property being leased is located in Northern California, a lease agreement is required to be both written and signed by the lessor if the lease period is for 6 months or more

Now, California has some principles that guide the regulation of the real estate industry and according to the California Principles of Real State, it has to be said that leases of less than one year are not required to be in writing.

Now, even though the law stated that the consent of both parties are not enough to bind themselves in the lease agreement, it is recommended that just for the sake of keeping things legally binding as regards the agreement between both parties, then both parties may state it in written and the lessor must sign it.
