When 1. 57 mol o2 reacts with h2 to form h2o , how many moles of h2 are consumed in the process?.

SAT

ddd [48]2 years ago
5 0

Consult the balanced reaction:

O₂ + 2 H₂   ⇄   2 H₂O

which says you need twice as many moles of H₂ as O₂. So if 1.57 mol O₂ is available, then the reaction would consume 2 × 1.57 = 3.14 mol H₂.

UNO [17]

Answer:

A research was interested in whether there was a difference in appearance management by

gender and the situation context. For example, on a romantic date, group date or out with

friends. Using the data provided determine whether there are statistically significant

differences in appearance management (measured in seconds) by gender and situational

context. Include all four hypothesis testing steps and α = .05 level of significance.

N = 36

n = 6

K = 6

G = 258

∑x2 = 2406

In the xy-plane, if (0,0) is a solution to the inequalities above, which of the following relationships between a+b must be true
natali 33 [55]
  • a must be greater than zero
  • b must be less than zero

<h2>Explanation:</h2>

The complete question is written in a comment above. The system of inequalities is the following:

\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}yx+b\end{array}\right.

So, in order to find a \ and \b you just need to replace both x and y-coordinates into our system. Therefore:

\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}00+b\end{array}\right. \\ \\ \\ Solving: \\ \\ \begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}0b\end{array}\right. \\ \\ \\ Finally: \\ \\ \begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}a>0\\b

So the conclusion is:

  • a must be greater than zero
  • b must be less than zero
