Answer:
3 moles of water are produced
Step-by-step explanation:
Find the limiting reactant
3.0 moles of H2 x (2 moles of H2O/2moles of H2)=3.0 moles of H20--limiting reactant, so this is the maximum amount of product that can be produced! Hope this helps
1.8 moles of O2 x (2 moles of H20/1 moles of O2)=3.6 moles of H20
3.6 moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas.
What is mole ?In chemistry, a mole is a unit of measurement used to quantify the amount of a chemical. It is defined as the amount of a substance containing Avogadro's number of entities (about 6.022 x [tex]10^{23[/tex]particles). The mole is a unit of measurement that is used to express the amount of a substance in terms of its molecular or atomic count. The mole is especially important in chemical reactions, where it is used to balance the number of atoms or molecules present in the reactants and products.
We have the balanced Equation:
2[tex]H_2[/tex] + [tex]O_2[/tex] ----> 2[tex]H_2O[/tex]
As, 3.0 moles of Hydrogen gas reacts with 1.8 moles of oxygen gas.
So, 1.8 moles of [tex]O_2[/tex] x (2 moles of [tex]H_2O[/tex] /1 moles of [tex]O_2[/tex])
= 3.6 moles of [tex]H_2O[/tex]
Also, 3.0 moles of Water is the limiting reactant.

Answer:
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].

Answer:
She worked 12 hours as a carpenter and 18 hours as a blacksmith
Step-by-step explanation:
You can solve this problem using a system of equations:
where c represents hours worked as a carpenter, and b represents hours worked as a blacksmith;
c + b = 30
20c + 25b = 690
To solve this system, you can multiply the first equation by 20 and subtract it from the second to isolate b:
20c + 25b = 690
- 20c + 20b = 600
5b = 90
Now, you can solve for b:
5b = 90
b = 18 (divide both sides by 5)
Now that you know b, you can input it into the first equation to find c:
b + c = 30, where b = 18;
18 + c = 30 (replace b in the equation with 18 because of transitive property of equality)
c = 12 (subtract 18 from both sides of the equation))
What is the range of y = x 2 − 1 , given a domain of {–2, –1, 0, 1, 2}
The range of the function y = x² - 1 is {- 1, 0, 3}.
What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given, A function y = x² - 1.
The set of domains is {- 2, - 1, 0, 1, 2}.
The set of co-domain is {3, 0, - 1, 0, 3}.
We know range ⊆ codomain.
Therefore, The range is {- 1, 0, 3}.

Jackie has 54 fewer beads than Sally. If b stands for the number of beads Jackie has, write an
expression that represents the number of beads Sally has?
Answer:
b+54
Step-by-step explanation:
Since Jackie has 54 fewer beads than Sally, Sally has 54 more beads than Jackie. Since b is the number of beads that Jackie has, then Sally's beads would be 54 more than that thus it would be b+54.

Answer:
D. (+,-)
Step-by-step explanation:
Map it out!
Quadrant I's points will always be (+,+). It is located in the upper right section.
Quadrant II's points will always be (-,+). It is located in the upper left section.
Quadrant III's points will always be (-,-). It is located in the lower left section.
Quadrant IV's points will always be (+,-). It is located in the lower right section.
The x-coordinate and y-coordinate are both negative, which is the right statement. The best choice is B.
When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.
The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.
As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.
