a clear liquid from a flask is poured into another clear liquid in a beaker . which of the following resulted of this procedure would indicate a new substance was formed ?
Answers
Answer:
b
Step-by-step explanation:
the answer is b because both were clear liquids and now they turned yellow change in color is part of chemical reactions so b is correct
Final answer:
When a clear liquid is poured into another clear liquid, indications of a new substance having been formed include changes such as color alteration, temperature shift, gas bubble formation, precipitate occurrence, and changes in properties.
Explanation:
The question is asking about the observation that would indicate a new substance was formed when a clear liquid from a flask is poured into another clear liquid in a beaker. In chemistry, when two substances interact to form a new substance, it's called a chemical reaction. There are several indicators that a chemical reaction has occurred. These include: a change in color, a change in temperature (the mixture gets hotter or colder), the formation of gas bubbles, the formation of a precipitate (a solid that forms and settles out of a liquid mixture), and a change in properties (such as viscosity, odor, or taste).
Now applying this understanding to the question, pouring a clear liquid into another clear liquid and if any of the above mentioned changes occurs then we can safely conclude that a new substance has been formed. For example, if the clear liquid mixture changes color, heat is felt, gas bubbles are formed or a solid precipitate settles at the bottom, these are undeniable signs of a new substance resulting from a chemical reaction.

Troll 2: Troll 1 is lying.
Troll 3: Either we are all knaves or at least one of us is a knight.
Which troll is which?
Answers
Troll 1: Knight
Troll 2: Knave
Troll 3: Knight
The following information should be considered:
- Troll 3's statement should be true since they can only be knights or knaves, till all of them are knaves, at least one must be a knight.
- In the case when Troll 2 is a knight, so Troll 1 is knave, but if that were the case Troll 1's statement should be true, and since knaves do not tell the truth, this assumption is incorrect.
- In the case when Troll 2 is a knave, Troll 1 is a knight and his statement can be disregarded.

Answer:
Troll 1: Knight
Troll 2: Knave
Troll 3: Knight
Step-by-step explanation:
Troll 3's statement must be true because if they can only be knights or knaves, unless all of them are knaves, at least one must be a knight. Thus, Troll 3 is a knight.
If Troll 2 is a knight, then Troll 1 is knave, but if that were the case Troll 1's statement would be true, and since knaves do not tell the truth, this assumption is incorrect.
If Troll 2 is a knave, Troll 1 is a knight and his statement can be disregarded since it is conditioned to the possibility of him being a knave.
Therefore, Trolls 1 and 3 are knights and Troll 2 is a knave.

Answer:
B. The caulk and super glue
Step-by-step explanation:
An impulse purchase is when you decide to buy something you didn't plan to in the spur of the moment. For example, when you are shopping your groceries and you decide to buy a product you see and that you don't have in your list. According to this, the two products that were impulse purchases are caulk and super glue because Natalie didn't plan to buy these products and she decided to do it when she was in the checkout line to pay for the other products that she planned to buy.

Note: A "quadratic function" takes the form of:
__________________________________________________
f(x) = ax² + bx + c ;
_________________________________________________
Answer choice: [D]: " H(x) = 3x(x - 2) - 4 " ;
takes this form:
_________________________________________________
" H(x) = 3x(x - 2) - 4 " ;
→ " 3x(x - 2) - 4 " ;
Note the "distributive property" of multiplication:
_________________________________________________
a(b + c) = ab + ac ; AND
a(b - c) = ab - ac ;
_________________________________________________
→ As such;
" 3x(x - 2) = (3x * x) - (3x * 2) = 3x² - 6x;
So, we can rewrite the expression:
→ " 3x(x - 2) - 4 " ;
as: → " 3x² - 6x - 4 ;
And the entire function as:
H(x) = 3x(x - 2) - 4 ;
as:
H(x) = 3x² - 6x - 4 ;
Which takes the form of a "quadratic function" ;
→ f(x) = ax² + bx + c ;
in which: a = 3 ; b = - 6 ; c = - 4 .
