How do you get rid of negative exponents?
Negative exponents indicate that the number for which the exponent applies to should be placed under one. Ex: 2^(-3) also can be expressed as 1/(2^3) or 1/8. So, to eliminate the negative exponent, simply place the number (and the accompanying exponent) under one to make a fraction.
What is 2 times a negative 2?
When multiplying a number by a negative number, the result is always negative. Therefore, 2 times a negative 2 is -4. This can be calculated by multiplying 2 by -2, resulting in -4 as the product.
What is negative 2 multiplied by negative 2?
A negative multiplied by a negative gives a positive, so the answer is 4.
What is negative 2 minus 2?
Negative four (-4).-2 - 2 = -4
Answer to negative 4 divided by negative 2?
2
Reduction occurs at which electrode?
The electrode that removes ions from solution
How do you make lead from lead 2 bromide?
Lead can be obtained from lead (II) bromide through a process called electrolysis. When lead (II) bromide is melted and electrolyzed, the lead ions migrate to the negative electrode (cathode) and are reduced to form lead metal, while bromide ions move to the positive electrode (anode) and are oxidized to produce bromine gas. This allows for the isolation of lead from lead (II) bromide.
Do you tig weld on dc straight or reverse polarity?
Tig is always done in straight polarity, i.e. electrode negative. reason: almost 2/3rd of the heat is generated in positive terminal of weld, in this case the base metal and the rest in the negative terminal, in this case the tungsten electrode. Also you don't want to deposit the tungsten electrode in the weld, do you?
What does the 2 stand for in 6027 electrode?
The "2" in a 6027 electrode typically refers to the electrode classification. In this case, it indicates that the electrode is classified as a low-hydrogen, iron powder electrode. It specifies the type of welding process, position, and characteristics of the electrode.
Why is lead placed in group 1 and 2 of the periodic table?
Lead is not placed in 1 or 2 group of periodic table, it is in IV-A (14th) group of periodic table, however in the scheme of salt analysis it is placed in ist and 2nd groups of basic radicals.
What is excess weaving in welding?
excessive We were taught 2-1/2 times the width of the electrode was maximum. ie: 5/16" width weld bead for 1/8" electrode.
What temperature is negative 2 degrees c?
Negative 2 degrees Celsius is below freezing point, which is 0 degrees Celsius. It is a cold temperature that can lead to frost formation and icy conditions.
What happen when electricity pass through copper sulphate solution?
When electricity passes through a copper sulfate solution, the copper sulfate dissociates into its ions: Cu2+ and SO4 2-. The Cu2+ ions move towards the cathode (negative electrode) and get reduced to form copper metal while SO4 2- ions move towards the anode (positive electrode) where they may undergo various reactions.
What is earth lead?
1.THE EARTH LEAD OR CONTROL PROTECTION CIRCUIT IN ELECT RIC FIELD CAN BE REFERRED AS: the finally brought back wire(cable)to the consumer's earth terminal and the earting lead connects this terminal to the earth electrode 2.EARTH ELECTRODE; can be referred as the electrode which makes connection to the general mass.it may be a cooper rod,tape or plateor a constructed lattice-type metal material depending onthe nature of the sub soil.Mr maganga from songea,Tanzania

Does a negative plus a negative plus a negative equal a negative?
A negative + a negative + a negative equals a negative. Adding a negative number is equal to subtracting a positive number. For example: -2+(-2)+(-2) = (-2)-2-2 -2+(-2)+(-2) = (-4)-2 -2+(-2)+(-2) = (-6)
Can the saturated calomel reference electrode be used in strong alkaline media such as 2-5 N KOH solution?
No, the saturated calomel reference electrode is not suitable for use in strong alkaline solutions like 2-5 N KOH. The high pH environment can damage the electrode and affect its performance. It is better to use a reference electrode designed specifically for use in alkaline media, such as a silver/silver chloride electrode.
