- How do you graph y = 1 5x + 3 and find the intercepts? - Socratic
First find and plot the intercept points (see below) then draw a line through those points to graph the equation The y-intercept is the value of y when x=0 Evaluating y=1 5x+3 with x=0 gives y=1 5 * 0 + 3 =3 So the y-intercept is at y=3 or the point (0,3) Similarly, the x-intercept is the value of x when y=0 Evaluating y=1 5x+3 with y=0 gives 0 = 1 5x+3 rarr 1 5x=-3 rarr x=-15 So the x
- How many protons are in lithium atom? - Socratic
Well, if you inspect your periodic table for a few minutes, you should find that lithium is the third element, i e with atomic number 3 Each element's atomic number, Z, indicates the number of protons in its nucleus Therefore, lithium has three protons What is lithium's electron configuration? What group is it in?
- Is BCl_3 a lewis acid? - Socratic
Boron trichloride is a potent Lewis acid, Boron trichloride is probably the most potent Lewis acid known, and will form adducts with ethers, halides, and amines While boron trifluoride is also Lewis-acidic, counter-intuitively, the lone pairs on the fluoride, are the right size and shape to donate electron density to the electron deficient boron atom, and the Lewis-acidity of BF_3 is somewhat
- How do you solve for c in P= a + 3+ c? - Socratic
Substract #color(red)(a)# and #color(blue)(3)# from each side of the equation to solve for #c# while keeping the equation balanced:
- How do you combine #(6- 4n ^ { 3} - 3n ^ { 4} ) - ( 4n - Socratic
See a solution process below: First, remove all of the terms from parenthesis Be careful to handle the signs of each individual term correctly: 6 - 4n^3 - 3n^4 - 4n^4 + 4n + 3n^3 Next, group like terms in descending order of the exponents: -4n^4 - 3n^4 + 3n^3 - 4n^3 + 4n + 6 Now, combine like terms: (-4 - 3)n^4 + (3 - 4)n^3 + 4n + 6 -7n^4 + (-1)n^3 + 4n + 6 -7n^4 -1n^3 + 4n + 6 -7n^4 - n^3
- Question #ebf5e + Example - Socratic
The equation tells you that 1 mole of citric acid reacts with 3 moles of NaOH, so you must have had (0 002 3) = 0 00067 moles of citric acid in your orange juice The molar mass of citric acid is 192 12 g, so 0 00067 moles is 192 12 x 0 00067 = 0 1287 g of citric acid The % of citric acid was therefore: #(0 1287 120) 100 = 0 1073%#
- How do you simplify #(\frac { 1} { x } ) ^ { 3}#? - Socratic
(1 x)^3=1 x^3=x^-3 There are multiple ways we can approach this Remember that an exponent really just is a way of talking about repeated multiplication: a^b=overbrace(a*a*a* *a*a)^(b" times") So, (1 x)^3=1 x*1 x*1 x Multiply these fractions like you normally would any fractions: (1 x)^3=(1*1*1) (x*x*x) Recall that x*x*x=x^3: (1 x)^3=1 x^3 We can also use the rule (a b)^n=a^n b^n to show
- How do you write 3 3 4 an improper fraction? - Socratic
15 4 An improper fraction has all the whole numbers converted in to quarters (in this question) along with the original fraction So in three whole numbers there are four quarters in each number making a total of 12 quarters, add the three quarters and you have a total of 15 quarters The rule is to multiply the whole number by the denominator ( the number on the bottom of the fraction) and
